Redis: Bug in XACKDEL may lead to stack overflow and potential RCE (CVE-2025-62507)
A vulnerability in Redis versions 8.2.0 through 8.2.2 allows a user to trigger a stack buffer overflow by running the XACKDEL command with multiple IDs. This flaw may lead to remote code execution. The issue is fixed in Redis version 8.2.3. As a workaround, administrators can restrict the XACKDEL command using ACLs to prevent exploitation without applying the patch.
AI Analysis
Technical Summary
Redis, an open source in-memory database, contains a stack buffer overflow vulnerability in the XACKDEL command when executed with multiple IDs in versions 8.2.0 and above up to but not including 8.2.3. This vulnerability (CVE-2025-62507) may allow an attacker to achieve remote code execution. The flaw is resolved in version 8.2.3. A mitigation without patching involves restricting the XACKDEL command via Access Control Lists (ACLs).
Potential Impact
Successful exploitation of this vulnerability can lead to a stack buffer overflow, potentially allowing remote code execution on the affected Redis server. This could compromise the confidentiality, integrity, and availability of the database and underlying system. No known exploits are reported in the wild at this time.
Mitigation Recommendations
A patch is available and the issue is fixed in Redis version 8.2.3. Users are advised to upgrade to this version to remediate the vulnerability. As a temporary workaround, administrators can restrict the execution of the XACKDEL command using ACLs to prevent exploitation until the patch can be applied.
