Unauthenticated memory disclosure via exposed syslog buffer
Published Apr 24, 2020 · Updated Aug 4, 2024
Information disclosure in Nanometrics Centaur 4.3.23 and earlier and TitanSMA 4.2.20 and earlier allows remote attackers to read shared memory. The embedded Jetty HTTP server accepts malformed header bytes that bleed up to 17 bytes from reused shared buffers into the unprotected syslog log. No authentication or user interaction is required; repeated requests and log retrieval expose fragments that can be combined to recover sensitive session data.
