Details

The web server used by MikroTik RouterOS version 6 is affected by a heap memory corruption issue. A remote and unauthenticated attacker can corrupt the server's heap memory by sending a crafted HTTP request. As a result, the web interface crashes and is immediately restarted. The issue was fixed in RouterOS 6.49.10 stable. RouterOS version 7 is not affected.

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.
