GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

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
