CISA KEV Advisory
Microsoft SQL Server Reporting Services Remote Code Execution Vulnerability
Microsoft SQL Server Reporting Services contains a deserialization vulnerability when handling page requests incorrectly. An authenticated attacker can exploit this vulnerability to execute code in the context of the Report Server service account.
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Risk Analysis
This deserialization vulnerability in Microsoft SQL Server Reporting Services allows an authenticated attacker to execute code in the context of the Report Server service account. The very high EPSS score of 0.94252 indicates a strong likelihood of exploitation, and its inclusion in the KEV confirms it is actively exploited.
This vulnerability is actively exploited in the wild, meaning that functional exploits are available and being used by threat actors. While authentication is required, it is remotely exploitable.
Apply all available security updates for Microsoft SQL Server Reporting Services. Ensure that the Report Server service account operates with the principle of least privilege.
Technical Analysis
CVE-2020-0618 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-2020-0618 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.
