VAR-200101-0033

Vulnerability from variot - Updated: 2025-04-03 22:23

Buffer overflow in IIS ISAPI .ASP parsing mechanism allows attackers to execute arbitrary commands via a long string to the "LANGUAGE" argument in a script tag. The ASP ISAPI file parser does not properly execute certain malformed ASP files that contain scripts with the LANGUAGE parameter containing a buffer of over 2200 characters and have the RUNAT value set as 'server'. Depending on the data entered into the buffer, a denial of service attack could be launched or arbitrary code could be executed under the SYSTEM privilege level in the event that a malicious ASP file were locally executed on IIS

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.
