Details

LIVE555 before 2026.04.22 contains an authorization bypass vulnerability in RTSP session command handling that allows attackers to replay valid Session tokens from unauthenticated connections. Attackers who obtain a valid Session token can issue PLAY and TEARDOWN commands from a second TCP connection without authentication, causing server crashes through virtual function call errors or disrupting active streams by terminating victim sessions.

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.

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
