Preliminary research
ATT&CKing TACACS+ to Pwn Your Network via a Pre-Auth RCE
AI-collected research leads through 6 October 2026, including bounded month-by-month reviews of selected social and community sources from January through September. Unranked, incomplete, not community-vetted, and subject to change.
Combines a predictable-error TACACS+ secret oracle with a pre-authentication format-string flaw in tac_plus. A laboratory login-client path lets an oversized username move attacker-controlled bytes into the NAS-port field without knowing the shared secret. Demonstrated RCE targets i386 with ASLR and NX disabled; a hardened production exploit and vendor HTTP login deployment are not established.
