Impacted is the function cgi_addgroup_get_group_quota_minsize of the file /cgi-bin/account_mgr.cgi. The manipulation of the argument Name results in stack-based buffer overflow. The attack may be performed from remote. The exploit has been made public and could be used."

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.
