CVE-2026-25075 (GCVE-0-2026-25075)

Vulnerability from nvd – Published: 2026-03-23 18:33 – Updated: 2026-05-06 14:41

Title

strongSwan 4.5.0 < 6.0.5 EAP-TTLS AVP Parsing Integer Underflow

Summary

strongSwan versions 4.5.0 prior to 6.0.5 contain an integer underflow vulnerability in the EAP-TTLS AVP parser that allows unauthenticated remote attackers to cause a denial of service by sending crafted AVP data with invalid length fields during IKEv2 authentication. Attackers can exploit the failure to validate AVP length fields before subtraction to trigger excessive memory allocation or NULL pointer dereference, crashing the charon IKE daemon.

Severity

8.7 (High)

CVE-2026-25998 (GCVE-0-2026-25998)

Vulnerability from nvd – Published: 2026-02-19 15:51 – Updated: 2026-02-20 15:42

Title

strongMan vulnerable to private credential recovery due to key and counter reuse

Summary

strongMan is a management interface for strongSwan, an OpenSource IPsec-based VPN. When storing credentials in the database (private keys, EAP secrets), strongMan encrypts the corresponding database fields. So far it used AES in CTR mode with a global database key. Together with an initialization vector (IV), a key stream is generated to encrypt the data in the database fields. But because strongMan did not generate individual IVs, every database field was encrypted using the same key stream. An attacker that has access to the database can use this to recover the encrypted credentials. In particular, because certificates, which have to be considered public information, are also encrypted using the same mechanism, an attacker can directly recover a large chunk of the key stream, which allows them to decrypt basically all other secrets especially ECDSA private keys and EAP secrets, which are usually a lot shorter. Version 0.2.0 fixes the issue by switching to AES-GCM-SIV encryption with a random nonce and an individually derived encryption key, using HKDF, for each encrypted value. Database migrations are provided to automatically re-encrypt all credentials.

Severity

8.7 (High)

CVE-2022-4967 (GCVE-0-2022-4967)

Vulnerability from nvd – Published: 2024-05-13 12:09 – Updated: 2025-02-13 16:38

Summary

strongSwan versions 5.9.2 through 5.9.5 are affected by authorization bypass through improper validation of certificate with host mismatch (CWE-297). When certificates are used to authenticate clients in TLS-based EAP methods, the IKE or EAP identity supplied by a client is not enforced to be contained in the client's certificate. So clients can authenticate with any trusted certificate and claim an arbitrary IKE/EAP identity as their own. This is problematic if the identity is used to make policy decisions. A fix was released in strongSwan version 5.9.6 in August 2022 (e4b4aabc4996fc61c37deab7858d07bc4d220136).

When certificates are used to authenticate clients in TLS-based EAP methods, the IKE or EAP identity supplied by a client is not enforced to be contained in the client\u0027s certificate. So clients can authenticate with any trusted certificate and claim an arbitrary IKE/EAP identity as their own. This is problematic if the identity is used to make policy decisions. A fix was released in strongSwan version 5.9.6 in August 2022 (e4b4aabc4996fc61c37deab7858d07bc4d220136)."

CVE-2023-26463 (GCVE-0-2023-26463)

Vulnerability from nvd – Published: 2023-04-14 00:00 – Updated: 2025-02-13 16:44

Summary

strongSwan 5.9.8 and 5.9.9 potentially allows remote code execution because it uses a variable named "public" for two different purposes within the same function. There is initially incorrect access control, later followed by an expired pointer dereference. One attack vector is sending an untrusted client certificate during EAP-TLS. A server is affected only if it loads plugins that implement TLS-based EAP methods (EAP-TLS, EAP-TTLS, EAP-PEAP, or EAP-TNC). This is fixed in 5.9.10.

Severity

9.8 (Critical)

CVE-2022-40617 (GCVE-0-2022-40617)

Vulnerability from nvd – Published: 2022-10-31 00:00 – Updated: 2025-05-06 18:29

Summary

strongSwan before 5.9.8 allows remote attackers to cause a denial of service in the revocation plugin by sending a crafted end-entity (and intermediate CA) certificate that contains a CRL/OCSP URL that points to a server (under the attacker's control) that doesn't properly respond but (for example) just does nothing after the initial TCP handshake, or sends an excessive amount of application data.

Severity

7.5 (High)

CVE-2021-41991 (GCVE-0-2021-41991)

Vulnerability from nvd – Published: 2021-10-18 13:44 – Updated: 2024-08-04 03:22

Summary

The in-memory certificate cache in strongSwan before 5.9.4 has a remote integer overflow upon receiving many requests with different certificates to fill the cache and later trigger the replacement of cache entries. The code attempts to select a less-often-used cache entry by means of a random number generator, but this is not done correctly. Remote code execution might be a slight possibility.

Severity

No CVSS data available.

CVE-2026-25075 (GCVE-0-2026-25075)

Vulnerability from cvelistv5 – Published: 2026-03-23 18:33 – Updated: 2026-05-06 14:41

Title

strongSwan 4.5.0 < 6.0.5 EAP-TTLS AVP Parsing Integer Underflow

Summary

strongSwan versions 4.5.0 prior to 6.0.5 contain an integer underflow vulnerability in the EAP-TTLS AVP parser that allows unauthenticated remote attackers to cause a denial of service by sending crafted AVP data with invalid length fields during IKEv2 authentication. Attackers can exploit the failure to validate AVP length fields before subtraction to trigger excessive memory allocation or NULL pointer dereference, crashing the charon IKE daemon.

CVE-2026-25998 (GCVE-0-2026-25998)

Vulnerability from cvelistv5 – Published: 2026-02-19 15:51 – Updated: 2026-02-20 15:42

Title

strongMan vulnerable to private credential recovery due to key and counter reuse

Summary

strongMan is a management interface for strongSwan, an OpenSource IPsec-based VPN. When storing credentials in the database (private keys, EAP secrets), strongMan encrypts the corresponding database fields. So far it used AES in CTR mode with a global database key. Together with an initialization vector (IV), a key stream is generated to encrypt the data in the database fields. But because strongMan did not generate individual IVs, every database field was encrypted using the same key stream. An attacker that has access to the database can use this to recover the encrypted credentials. In particular, because certificates, which have to be considered public information, are also encrypted using the same mechanism, an attacker can directly recover a large chunk of the key stream, which allows them to decrypt basically all other secrets especially ECDSA private keys and EAP secrets, which are usually a lot shorter. Version 0.2.0 fixes the issue by switching to AES-GCM-SIV encryption with a random nonce and an individually derived encryption key, using HKDF, for each encrypted value. Database migrations are provided to automatically re-encrypt all credentials.

Severity

8.7 (High)

CVE-2022-4967 (GCVE-0-2022-4967)

Vulnerability from cvelistv5 – Published: 2024-05-13 12:09 – Updated: 2025-02-13 16:38

Summary

strongSwan versions 5.9.2 through 5.9.5 are affected by authorization bypass through improper validation of certificate with host mismatch (CWE-297). When certificates are used to authenticate clients in TLS-based EAP methods, the IKE or EAP identity supplied by a client is not enforced to be contained in the client's certificate. So clients can authenticate with any trusted certificate and claim an arbitrary IKE/EAP identity as their own. This is problematic if the identity is used to make policy decisions. A fix was released in strongSwan version 5.9.6 in August 2022 (e4b4aabc4996fc61c37deab7858d07bc4d220136).

CVE-2023-26463 (GCVE-0-2023-26463)

Vulnerability from cvelistv5 – Published: 2023-04-14 00:00 – Updated: 2025-02-13 16:44

Summary

strongSwan 5.9.8 and 5.9.9 potentially allows remote code execution because it uses a variable named "public" for two different purposes within the same function. There is initially incorrect access control, later followed by an expired pointer dereference. One attack vector is sending an untrusted client certificate during EAP-TLS. A server is affected only if it loads plugins that implement TLS-based EAP methods (EAP-TLS, EAP-TTLS, EAP-PEAP, or EAP-TNC). This is fixed in 5.9.10.

Severity

9.8 (Critical)

CVE-2022-40617 (GCVE-0-2022-40617)

Vulnerability from cvelistv5 – Published: 2022-10-31 00:00 – Updated: 2025-05-06 18:29

Summary

strongSwan before 5.9.8 allows remote attackers to cause a denial of service in the revocation plugin by sending a crafted end-entity (and intermediate CA) certificate that contains a CRL/OCSP URL that points to a server (under the attacker's control) that doesn't properly respond but (for example) just does nothing after the initial TCP handshake, or sends an excessive amount of application data.

Severity

7.5 (High)

CVE-2021-41991 (GCVE-0-2021-41991)

Vulnerability from cvelistv5 – Published: 2021-10-18 13:44 – Updated: 2024-08-04 03:22

Summary

The in-memory certificate cache in strongSwan before 5.9.4 has a remote integer overflow upon receiving many requests with different certificates to fill the cache and later trigger the replacement of cache entries. The code attempts to select a less-often-used cache entry by means of a random number generator, but this is not done correctly. Remote code execution might be a slight possibility.

Severity

No CVSS data available.

Debian Security Advisory DSA-4989-1 security@debian.org https://www.debian.org/security/ Yves-Alexis Perez October 18, 2021 https://www.debian.org/security/faq

Package : strongswan CVE ID : CVE-2021-41990 CVE-2021-41991

Researchers at the United States of America National Security Agency (NSA) identified two denial of services vulnerability in strongSwan, an IKE/IPsec suite.

CVE-2021-41990

RSASSA-PSS signatures whose parameters define a very high salt length can
trigger an integer overflow that can lead to a segmentation fault. 
Generating a signature that bypasses the padding check to trigger the crash
requires access to the private key that signed the certificate.  However,
the certificate does not have to be trusted.  Because the gmp and the
openssl plugins both check if a parsed certificate is self-signed (and the
signature is valid), this can e.g.  be triggered by an unrelated
self-signed CA certificate sent by an initiator. Depending on the generated random value, this could
lead to an integer overflow that results in a double-dereference and a call
using out-of-bounds memory that most likely leads to a segmentation fault. 
Remote code execution can't be ruled out completely, but attackers have no
control over the dereferenced memory, so it seems unlikely at this point.

For the oldstable distribution (buster), these problems have been fixed in version 5.7.2-1+deb10u1.

For the stable distribution (bullseye), these problems have been fixed in version 5.9.1-1+deb11u1.

We recommend that you upgrade your strongswan packages.

However,\n    the certificate does not have to be trusted.  Because the gmp and the\n    openssl plugins both check if a parsed certificate is self-signed (and the\n    signature is valid), this can e.g.  be triggered by an unrelated\n    self-signed CA certificate sent by an initiator. Depending on the generated random value, this could\n    lead to an integer overflow that results in a double-dereference and a call\n    using out-of-bounds memory that most likely leads to a segmentation fault. \n    Remote code execution can\u0027t be ruled out completely, but attackers have no\n    control over the dereferenced memory, so it seems unlikely at this point. \n\nFor the oldstable distribution (buster), these problems have been fixed\nin version 5.7.2-1+deb10u1. \n\nFor the stable distribution (bullseye), these problems have been fixed in\nversion 5.9.1-1+deb11u1. \n\nWe recommend that you upgrade your strongswan packages. \n\nFor the detailed security status of strongswan please refer to\nits security tracker page at:\nhttps://security-tracker.debian.org/tracker/strongswan\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n\niQEzBAEBCgAdFiEE8vi34Qgfo83x35gF3rYcyPpXRFsFAmFtyAUACgkQ3rYcyPpX\nRFudiwf+NNcRRRJychLI5ycMKVxkr2tEAJDeVZjv966YBM1tXnCtROydXf5Zip2M\ndn/EYO71uuT5FKhs8tJyx5iv2bFcrvyqQQo6DFQvXZHR0+9U+MHcR9qB7JJDM4nK\n+JXOEmAv3akCFhiP6jMx5B6jRWR1e4MOwxmgrgGu/nwy2cYBQPI43qPTrXi3Fcnv\neSgeyLqyZNLmaGmj8jQfTnc8bdVF5xAs6mHhVqNJxQCdouG9b4/S6AxJsl3IMxyF\nWZhtCNUvhHH8wz0lZVElR3Qs6fUu0phKdlT9kBv/o6fP3ceiYOCEh8SqBgYU3hQL\nxyB0uP4EcSR70TvKZMB2jV/tGG1A8w==\n=/Xvi\n-----END PGP SIGNATURE-----\n. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\nGentoo Linux Security Advisory                           GLSA 202405-08\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n                                           https://security.gentoo.org/\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\n Severity: Normal\n    Title: strongSwan: Multiple Vulnerabilities\n     Date: May 04, 2024\n     Bugs: #818841, #832460, #878887, #899964\n       ID: 202405-08\n\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\nSynopsis\n=======\nMultiple vulnerabilities have been discovered in strongSwan, the worst\nof which could possibly lead to remote code execution. \n\nBackground\n=========\nstrongSwan is an IPSec implementation for Linux. \n\nAffected packages\n================\nPackage             Vulnerable    Unaffected\n------------------  ------------  ------------\nnet-vpn/strongswan  \u003c 5.9.10      \u003e= 5.9.10\n\nDescription\n==========\nMultiple vulnerabilities have been discovered in strongSwan.
