Apache Roller – Critical session management vulnerability
Apache Roller – Critical session management vulnerability
Summary
A critical session management vulnerability, CVE-2025-24859, affects Apache Roller—a Java-based open-source blogserver. This flaw enables persistent unauthorized access through valid session tokens, even after user passwordresets. Versions from 1.0.0 up to and including 6.1.4
are vulnerable. The issue is resolved in version 6.1.5, whichintroduces centralized session invalidation mechanisms.
Affected Systems and/or Applications
- Product: Apache Roller
- Affected Versions: 1.0.0 through 6.1.4
- Fixed Version: 6.1.5
Technical Details
The vulnerability stems from insufficient session expiration handling. Specifically, when a user’s password ischanged—either by the user or an administrator—existing sessions are not properly invalidated. Consequently, anyactive session tokens remain valid, allowing an attacker who has obtained such a token to continue accessing theapplication without interruption. This issue is categorized under CWE-613: Insufficient Session Expiration.
Attack Scenario
- An attacker acquires a user’s session token (e.g., via phishing or session hijacking).
- The legitimate user changes their password, expecting to terminate all sessions.
- Due to the flaw, the attacker’s session remains active, granting continued unauthorized access.
This vulnerability undermines the effectiveness of password changes as a security measure, potentially leading toprolonged unauthorized access and data compromise.
Fix Details
- Apache Roller 6.1.5 introduces:
- A centralized session management framework.
- Automatic invalidation of all user sessions upon password changes and deactivation.
Mitigation
- Immediate Action: Upgrade Apache Roller to version 6.1.5 or later.
- Temporary Measures (if immediate upgrade is not feasible):
- Monitor user session activities closely.
- Use a Web Application Firewall (WAF) to limit session duration and flag anomalies.
