Executive brief
upKeeper Instant Privilege Access is a tool used to manage temporary administrative rights on Windows systems. A vulnerability in its logging system allows an attacker to inject or forge log entries, which can be used to hide malicious activity or mislead administrators during an investigation. This compromises the integrity of the audit trail, making it difficult to verify who performed specific actions on the network.
Technical details
A log injection vulnerability (CWE-117) exists in upKeeper Instant Privilege Access through version 1.6.1 on Windows. The application fails to properly neutralize user-supplied input before it is written to system logs, allowing a remote attacker to inject newlines and forge log entries. While the primary impact is on the integrity and accountability of the logging system (Subsequent System Integrity/Availability), it can be used to mask unauthorized privilege escalation or other malicious maneuvers. The vulnerability is reachable over the network without prior authentication.
