Gunet Open Eclass Platform ≤ 4.2
Raw vector
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HSummary
CVE-2026-24669 is a high-severity Insufficient Session Expiration (CWE-613) vulnerability in Gunet Open Eclass Platform. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Browser Session Hijacking (T1185); ranked at the 5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-12 (Session Termination) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-24669 affects the Open eClass platform, formerly known as GUnet eClass, which is a complete course management system. Prior to version 4.2, the platform's password reset mechanism is insecure, allowing local attackers to reuse a valid password reset token even after it has already been used once. This flaw, classified under CWE-613 (Insufficient Session Expiration), enables unauthorized password changes and potential account takeover. The vulnerability carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high impact with local access required.
Local attackers with no privileges can exploit this issue by capturing or reusing a previously consumed password reset token, though it requires user interaction such as clicking a malicious link or providing input. Successful exploitation allows the attacker to reset the password of a targeted account, leading to full account takeover with high confidentiality, integrity, and availability impacts.
The issue has been addressed in Open eClass version 4.2. Security practitioners should upgrade to this patched version immediately. Additional details are available in the GitHub security advisory at https://github.com/gunet/openeclass/security/advisories/GHSA-gcqq-fxw6-f866.

AC-12 directly requires automatic session termination after a defined period, structurally preventing reuse of expired session identifiers.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Credential lifecycle management directly includes enforcing session expiration to prevent reuse.
Authorization policy enforcement and review covers terminating stale sessions to limit access scope.
Authentication mechanisms can incorporate session timeout checks but do not inherently address expiration policy.

Automatic termination of inactive sessions and limits on connection duration shrink the window during which a hijacked or unattended authenticated session can be exploited.
