Description

For Eclipse Jetty versions <= 9.4.40, <= 10.0.2, <= 11.0.2, if an exception is thrown from the SessionListener#sessionDestroyed() method, then the session ID is not invalidated in the session ID manager. On deployments with clustered sessions and multiple contexts this can result in a session not being invalidated. This can result in an application used on a shared computer being left logged in.

Understanding This Vulnerability

This Common Vulnerabilities and Exposures (CVE) entry provides detailed information about a security vulnerability that has been publicly disclosed. CVEs are standardized identifiers assigned by MITRE Corporation to track and catalog security vulnerabilities across software and hardware products.

The severity rating (LOW) indicates the potential impact of this vulnerability based on the CVSS (Common Vulnerability Scoring System) framework. Higher severity ratings typically indicate vulnerabilities that could lead to more significant security breaches if exploited. Security teams should prioritize remediation efforts based on severity, exploit availability, and the EPSS (Exploit Prediction Scoring System) score, which predicts the likelihood of exploitation in the wild.

If this vulnerability affects products or systems in your infrastructure, we recommend reviewing the affected products section, checking for available patches or updates from vendors, and implementing recommended workarounds or solutions until a permanent fix is available. Organizations should also monitor security advisories and threat intelligence feeds for updates about active exploitation of this vulnerability.

SessionListener can prevent a session from being invalidated breaking logout

GHSA-m6cp-vxjx-65j6

Advisory Details

### Impact If an exception is thrown from the `SessionListener#sessionDestroyed()` method, then the session ID is not invalidated in the session ID manager. On deployments with clustered sessions and multiple contexts this can result in a session not being invalidated. This can result in an application used on a shared computer being left logged in. There is no known path for an attacker to induce such an exception to be thrown, thus they must rely on an application to throw such an exception. The OP has also identified that during the call to `sessionDestroyed`, the `getLastAccessedTime()` throws an `IllegalStateException`, which potentially contrary to the servlet spec, so applications calling this method may always throw and fail to log out. If such an application was only tested on a non clustered test environment, then it may be deployed on a clustered environment with multiple contexts and fail to log out. ### Workarounds The application should catch all Throwables within their `SessionListener#sessionDestroyed()` implementations.
