VAR-199911-0013

Vulnerability from variot - Updated: 2025-04-03 22:19

Idle locking function in MacOS 9 allows local attackers to bypass the password protection of idled sessions via the programmer's switch or CMD-PWR keyboard sequence, which brings up a debugger that the attacker can use to disable the lock. apple's macOS Exists in unspecified vulnerabilities.None. Under MacOS the key combination CMD-PWR (Command key + Power Key) or the programmer's switch (on models that have one) will start up the micro-debugger or an assembly debugger such as MacsBug. This behavior occurs even while the screen is locked after the user becoming idle. This allows a user to drop into the debugger and kill the screen lock process and obtain access to the desktop. There is a vulnerability in the idle lock function in the MacOS 9 version

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
