CISA KEV Advisory
Microsoft .NET Framework Information Disclosure Vulnerability
Microsoft .NET Framework contains an information disclosure vulnerability that exposes the ObjRef URI to an attacker, ultimately enabling remote code execution.
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Risk Analysis
Microsoft .NET Framework is affected by an information disclosure vulnerability that exposes the ObjRef URI, ultimately enabling remote code execution. With an EPSS score of 0.93859, the likelihood of exploitation is very high, and its inclusion in CISA's KEV confirms active exploitation, making this a critical vulnerability.
This vulnerability is actively being exploited in the wild, as confirmed by its 'in_the_wild' exploit status and inclusion in CISA's KEV. The nature of the flaw suggests it can be exploited remotely.
Organizations should ensure all systems running Microsoft .NET Framework are fully updated with the latest security patches. Implementing robust network segmentation and monitoring for unusual traffic patterns can help.
Technical Analysis
CVE-2024-29059 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2024-29059 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
