CVE-2026-87779: CWE-532 Insertion of sensitive information into log file in Apache Software Foundation Apache Syncope
Apache Syncope versions 3.0.15 through 3.0.16, 4.0.3 through 4.0.7, and 4.1.0-M0 through 4.1.2 contain a vulnerability where sensitive information, specifically the AES key after padding, is inserted into log files. This occurs when a non-standard length AES key is configured, causing Syncope to pad the key with random characters and log the resulting value. Upgrading to versions 4.0.8 or 4.1.3 addresses this issue.
AI Analysis
Technical Summary
The vulnerability in Apache Syncope involves the insertion of sensitive information into log files (CWE-532). When an AES key of non-standard length (not 16, 24, or 32 bytes) is configured, Syncope pads the key with random characters, and the padded key is logged. This behavior exposes sensitive cryptographic material in logs, potentially compromising security. The affected versions are from 3.0.15 through 3.0.16, 4.0.3 through 4.0.7, and 4.1.0-M0 through 4.1.2. The issue is fixed in versions 4.0.8 and 4.1.3.
Potential Impact
Sensitive cryptographic key material (AES key after padding) is written to log files, which may be accessible to unauthorized users with access to logs. This exposure can lead to compromise of encrypted data or cryptographic operations relying on the key. No known exploits in the wild have been reported.
Mitigation Recommendations
Users should upgrade Apache Syncope to version 4.0.8 or 4.1.3, where this vulnerability is fixed. No other mitigation steps are indicated.
