Summary
Ed25519 Signature Malleability in ed25519-java Due to Missing Scalar Range Check
Details

The implementation of EdDSA in EdDSA-Java (aka ed25519-java) through 0.3.0 exhibits signature malleability and does not satisfy the SUF-CMA (Strong Existential Unforgeability under Chosen Message Attacks) property. This allows attackers to create new valid signatures different from previous signatures for a known message.

Vulnerability from github – Published: 2026-04-03 21:31 – Updated: 2026-05-01 12:30
VLAI
Details

A flaw was found in rust-rpm-sequoia. An attacker can exploit this vulnerability by providing a specially crafted Red Hat Package Manager (RPM) file. During the RPM signature verification process, this crafted file can trigger an error in the OpenPGP signature parsing code, leading to an unconditional termination of the rpm process. This issue results in an application level denial of service, making the system unable to process RPM files for signature verification.

Vulnerability from github – Published: 2022-05-24 16:56 – Updated: 2024-04-04 01:59
VLAI
Details

A vulnerability in the Image Verification feature of Cisco IOS XE Software could allow an authenticated, local attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability exists because, under certain circumstances, an affected device can be configured to not verify the digital signatures of system image files during the boot process. An attacker could exploit this vulnerability by abusing a specific feature that is part of the device boot process. A successful exploit could allow the attacker to install and boot a malicious software image or execute unsigned binaries on the targeted device.

Vulnerability from github – Published: 2024-09-17 21:30 – Updated: 2025-03-14 21:41
VLAI
Summary
druid-pac4j, Apache Druid extension, has Padding Oracle vulnerability
Details

Padding Oracle vulnerability in Apache Druid extension, druid-pac4j. This could allow an attacker to manipulate a pac4j session cookie.

This issue affects Apache Druid versions 0.18.0 through 30.0.0. Since the druid-pac4j extension is optional and disabled by default, Druid installations not using the druid-pac4j extension are not affected by this vulnerability.

While we are not aware of a way to meaningfully exploit this flaw, we nevertheless recommend upgrading to version 30.0.1 or higher which fixes the issue and ensuring you have a strong druid.auth.pac4j.cookiePassphrase as a precaution.

Vulnerability from github – Published: 2022-05-24 19:11 – Updated: 2022-05-24 19:11
VLAI
Details

A vulnerability in the image verification function of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an authenticated, remote attacker to execute code with internal user privileges on the underlying operating system. The vulnerability is due to insufficient validation of the content of upgrade packages. An attacker could exploit this vulnerability by uploading a malicious archive to the Upgrade page of the administrative web interface. A successful exploit could allow the attacker to execute code with user-level privileges (the _nobody account) on the underlying operating system.

GHSA-P847-Q8VX-C3FG

Vulnerability from github – Published: 2026-07-16 06:31 – Updated: 2026-08-07 06:30
VLAI
Details

The SAML Single Sign On – SSO Login plugin for WordPress is vulnerable to Authentication Bypass via SAML Signature Algorithm Confusion in all versions up to, and including, 5.4.3. The vulnerability exists because Mo_SAML_Utilities::mo_saml_cast_key() reads the SignatureMethod Algorithm attribute directly from the attacker-controlled SAMLResponse parameter rather than enforcing the locally configured algorithm, causing the plugin to recast the IdP's RSA public key as an HMAC-SHA1 shared secret and validate the forged signature against it. This makes it possible for unauthenticated attackers to forge a SAML assertion targeting any WordPress account — including administrators — obtain valid WordPress authentication cookies, and achieve full administrator-level account takeover.

GHSA-P8C3-7RJ8-Q963

Vulnerability from github – Published: 2020-06-26 16:54 – Updated: 2023-01-31 01:29
VLAI
Summary
ECDSA signature validation vulnerability by accepting wrong ASN.1 encoding in jsrsasign
Details

Impact

Jsrsasign supports ECDSA signature validation which signature value is represented by ASN.1 DER encoding. This vulnerablity may accept a wrong ASN.1 DER encoded ECDSA signature such as:

  • wrong multi-byte ASN.1 length of TLV (ex. 0x820045 even though 0x45 is correct)
  • prepending zeros with ASN.1 INTEGER value (ex. 0x00000123 even though 0x0123 is correct)
  • appending zeros to signature of ASN.1 TLV (ex. 0x3082....1fbc000000 even though 0x3082....1fbc, appending zeros are ignored.)

This vulnerability was fixed by strict ASN.1 DER checking.

Here is an assessment of this vulnerability:

  • If you are not use ECDSA signature validation, this vulnerability is not affected.
  • Not ASN.1 format signature like just concatenation of R and S value is not affected such as Bitcoin.
  • This vulnerability is affected to all ECC curve parameters.
  • Risk to accept a forged or crafted message to be signed is low.
  • Risk to raise memory corruption is low since jsrsasign uses BigInteger class.
  • ECDSA signatures semantically the same to valid one may be accepted as valid. There are many malleable variants.

As discussed here, there is no standards like X9.62 which requires ASN.1 DER. So ASN.1 BER can be applied to ECDSA however most of implementations like OpenSSL do strict ASN.1 DER checking.

Patches

Users using ECDSA signature validation should upgrade to 8.0.19.

Workarounds

Do strict ASN.1 DER checking for ASN.1 encoded ECDSA signature value.

CAPEC-463: Padding Oracle Crypto Attack

An adversary is able to efficiently decrypt data without knowing the decryption key if a target system leaks data on whether or not a padding error happened while decrypting the ciphertext. A target system that leaks this type of information becomes the padding oracle and an adversary is able to make use of that oracle to efficiently decrypt data without knowing the decryption key by issuing on average 128*b calls to the padding oracle (where b is the number of bytes in the ciphertext block). In addition to performing decryption, an adversary is also able to produce valid ciphertexts (i.e., perform encryption) by using the padding oracle, all without knowing the encryption key.

CAPEC-475: Signature Spoofing by Improper Validation

An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
