Detailsinfo

A vulnerability has been found in Apache Syncope up to 2.1.14/3.0.14/4.0.2 and classified as problematic. Affected by this vulnerability is an unknown code block. The manipulation with an unknown input leads to a hard-coded key vulnerability. The CWE definition for the vulnerability is CWE-321. The use of a hard-coded cryptographic key significantly increases the possibility that encrypted data may be recovered. As an impact it is known to affect confidentiality. The summary by CVE is:

Apache Syncope can be configured to store the user password values in the internal database with AES encryption, though this is not the default option. When AES is configured, the default key value, hard-coded in the source code, is always used. This allows a malicious attacker, once obtained access to the internal database content, to reconstruct the original cleartext password values. This is not affecting encrypted plain attributes, whose values are also stored using AES encryption. Users are recommended to upgrade to version 3.0.15 / 4.0.3, which fix this issue.

The weakness was presented by Clemens Bergmann. The advisory is shared at lists.apache.org. This vulnerability is known as CVE-2025-65998 since 11/19/2025. The exploitation appears to be difficult. An attack has to be approached locally. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.

Upgrading to version 3.0.15 or 4.0.3 eliminates this vulnerability.
