Log spoofing via unsanitized agent UUID
Published Sep 21, 2022 · Updated May 27, 2025
Log injection in Keylime before 6.3.0 allows remote attackers to spoof registrar and verifier log entries through a crafted agent UUID. The registrar registration handler and verifier REST handlers log the attacker-controlled agent ID without rejecting newline characters. Network access to the unauthenticated registrar interface is sufficient, and forged journal entries can mislead administrators into taking harmful actions.
