Title
MISP Correlation Engine Fails to Refresh When Event Distribution or Sharing Group Changes
Summary
MISP contains a defect in its event save workflow that prevents the correlation engine from recalculating correlations when an event's distribution level or sharing group is modified.
When a user edits an existing event and changes its distribution or sharing_group_id, the internal before-save hook stored the incoming (new) data rather than the previously persisted values. As a result, the after-save comparison that determines whether a correlation refresh is needed never detected the change, and stale correlations persisted.
Security impact:
- Stale correlations may continue to expose event data to users in a broader sharing group after the event has been moved to a more restrictive group, resulting in unintended information disclosure.
- Conversely, newly relevant correlations may not appear after a distribution widening, degrading the completeness of threat intelligence sharing.
Preconditions:
- An authenticated user with write access to at least one MISP event.
- The user modifies the event's distribution or sharing_group_id field.

fix: [correlation] fix correlation distribution refresh on | a23e99457b84… |
Fix summary
The fix ensures that the before-save hook retrieves the previously persisted distribution and sharing_group_id values from the database for existing events, rather than capturing the incoming (new) data. This allows the after-save logic to correctly detect when these fields have changed and trigger a correlation refresh, ensuring access boundaries on correlated data are enforced promptly.
Patch summary
In app/Model/Event.php, the beforeSave method was modified. Previously, $this->__beforeSaveData was set to the full incoming $this->data['Event'] array. The patch replaces this with: (1) initializing __beforeSaveData to null, (2) checking whether the event has an existing id (i.e., it is an update, not a create), (3) issuing a targeted database query (recursive -1, selecting only Event.distribution and Event.sharing_group_id) to fetch the currently stored values, and (4) storing those fetched values in __beforeSaveData. This ensures the after-save comparison correctly identifies distribution/sharing_group_id changes.
CVSS rationale
AV:N: MISP is a network-accessible web application. AC:L: An authenticated user simply edits an event's sharing group; no race condition or complex setup is needed. AT:N: No manipulation of a separate attack target is required. PR:L: Requires an authenticated user with write access to events. UI:N: The stale correlation persists without further user interaction. VC/VI/VA:N: The vulnerable component (the event save logic) is not directly compromised in confidentiality, integrity, or availability. SC:L: The security impact is on the broader MISP instance: users in a broader sharing group may see correlation data referencing an event that was moved to a more restrictive group, resulting in limited information disclosure. SI/SA:N: No integrity or safety impact on other systems.
Weakness rationale
- CWE-284 The core security impact is that correlation data access boundaries are not enforced when an event's sharing group or distribution changes. Stale correlations can expose event data to users who should no longer have access, constituting an improper access control failure.
- CWE-665 The root cause is that the __beforeSaveData variable was initialized with the incoming (new) data rather than the previously stored data, causing the change-detection logic in afterSave to fail. This is a classic improper initialization of a state variable used for change detection.
Attack pattern rationale
- CAPEC-114 The closest plausible CAPEC is Parameter Tampering: a user modifies the distribution or sharing_group_id parameters of an event, and the application fails to properly enforce the resulting access-control changes on correlated data. The mapping is uncertain because this is not a malicious tamper per se but a legitimate parameter modification that exposes a system defect; however, CAPEC-114 best captures the scenario where parameter changes are not properly reflected in downstream access enforcement. No more specific CAPEC for 'stale derived data after parameter change' exists in the CAPEC catalog.
Assumptions to verify
- The exact fixed version number is not specified in the patch metadata; the tag boundary indicates the fix is 47 commits after v2.5.48, but the release tag containing this commit is unknown.
- The security impact is assessed as limited information disclosure through stale correlations; the patch does not indicate a direct privilege escalation or data corruption vector.
- CAPEC-114 (Parameter Tampering) is the closest available mapping; no CAPEC specifically covers 'stale derived data after a legitimate parameter change' and the mapping is approximate.
- The assumption that the afterSave hook uses __beforeSaveData to compare old vs new distribution/sharing_group_id values is inferred from the commit message and the code change pattern; the afterSave code itself is not included in the patch.
- CVSS UI:N assumes the stale correlation data is accessible via the normal MISP UI/API without additional user interaction beyond the initial event edit.
- The Co-Authored-By line for Claude Opus 4.8 is treated as a tool credit, not a human remediation developer.

Title
Suricata smtp/mime: incomplete state reset allows detection bypass
Summary
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, the SMTP MIME parser in rust/src/mime/smtp.rs does not fully reset state when processing Content-Type: message/rfc822 encapsulation. An outer MIME part's encoding or filename state can leak into the inner message, allowing crafted mail to evade detections based on file.data, file.name, or extracted URLs when SMTP MIME decoding is enabled. This issue is fixed in version 8.0.6.

Title
CoreWCF NetNamedPipe transport accepts attach to a pre-existing named pipe instance
Summary
CoreWCF is a port of the service side of Windows Communication Foundation (WCF) to .NET Core. Prior to 1.8.1 and 1.9.1, CoreWCF NetNamedPipe transport accepts attachment to a pre-existing named pipe instance, allowing local interception of NetNamedPipe traffic when an attacker races NamedPipeListener startup between shared memory GUID publication and service named pipe creation. This issue is fixed in versions 1.8.1 and 1.9.1.

Title
Quicly is vulnerable to stateless reset injection
Summary
Quicly is an IETF QUIC protocol implementation intended primarily for use within the H2O HTTP server. Prior to commit dccf5d4, Quicly was vulnerable to stateless reset injection through lack of packet entry validation. The QUIC protocol is designed to withstand packet injection attacks, once the handshake is complete. Only packets that carry some secret patterns are considered as stateless resets. Quicly allows the peer to share up to 4 such patterns per connection. However, until now, it failed to determine which of the 4 slots that it uses to retain the secret patterns contains a valid entry. As the slots are zero-initialized, the failure meant that, unless the peer advertised 4 of such patterns, an all-zero pattern was treated as a stateless reset.In effect, this allowed an on-path attacker to reset QUIC connections governed by Quicly. This issue has been fixed by commit dccf5d4.

Title
filippo.io/edwards25519 MultiScalarMult function produces invalid results or undefined behavior if receiver is not the identity
Summary
filippo.io/edwards25519 is a Go library implementing the edwards25519 elliptic curve with APIs for building cryptographic primitives. In versions 1.1.0 and earlier, MultiScalarMult produces invalid results or undefined behavior if the receiver is not the identity point. If (*Point).MultiScalarMult is called on an initialized point that is not the identity point, it returns an incorrect result. If the method is called on an uninitialized point, the behavior is undefined. In particular, if the receiver is the zero value, MultiScalarMult returns an invalid point that compares Equal to every other point. Note that MultiScalarMult is a rarely used, advanced API. For example, users who depend on filippo.io/edwards25519 only through github.com/go-sql-driver/mysql are not affected. This issue has been fixed in version 1.1.1.

"value": "filippo.io/edwards25519 is a Go library implementing the edwards25519 elliptic curve with APIs for building cryptographic primitives. In versions 1.1.0 and earlier, MultiScalarMult produces invalid results or undefined behavior if the receiver is not the identity point. If (*Point).MultiScalarMult is called on an initialized point that is not the identity point, it returns an incorrect result. If the method is called on an uninitialized point, the behavior is undefined. In particular, if the receiver is the zero value, MultiScalarMult returns an invalid point that compares Equal to every other point. Note that MultiScalarMult is a rarely used, advanced API. For example, users who depend on filippo.io/edwards25519 only through github.com/go-sql-driver/mysql are not affected. This issue has been fixed in version 1.1.1."

Mitigation MIT-3
Requirements
Strategy: Language Selection
- Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, in Java, if the programmer does not explicitly initialize a variable, then the code could produce a compile-time error (if the variable is local) or automatically initialize the variable to the default value for the variable's type. In Perl, if explicit initialization is not performed, then a default value of undef is assigned, which is interpreted as 0, false, or an equivalent value depending on the context in which the variable is accessed.
Mitigation
Architecture and Design
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Implementation
Explicitly initialize all your variables and other data stores, either during declaration or just before the first usage.
Mitigation
Implementation
Pay close attention to complex conditionals that affect initialization, since some conditions might not perform the initialization.
Mitigation
Implementation
Avoid race conditions (CWE-362) during initialization routines.
Mitigation
Build and Compilation
Run or compile your product with settings that generate warnings about uninitialized variables or data.
CAPEC-26: Leveraging Race Conditions
The adversary targets a race condition occurring when multiple processes access and manipulate the same resource concurrently, and the outcome of the execution depends on the particular order in which the access takes place. The adversary can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance, a race condition can occur while accessing a file: the adversary can trick the system by replacing the original file with their version and cause the system to read the malicious file.
CAPEC-29: Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. A typical example is file access. The adversary can leverage a file access race condition by "running the race", meaning that they would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the adversary could replace or modify the file, causing the application to behave unexpectedly.
