Technical Information
CVE-2024-8923 is a critical vulnerability affecting the ServiceNow Now Platform, a widely used enterprise cloud platform. The vulnerability is categorized as a Sandbox Escape, which is a type of security flaw that allows malicious actors to break out of a restricted execution environment, or "sandbox," and execute arbitrary code on the host system. This particular vulnerability arises from an input validation error, which can be exploited by unauthenticated users to perform Remote Code Execution (RCE). The CVSS score of 9.8 underscores the critical nature of this flaw, highlighting the potential for severe impact on affected systems.
The vulnerability affects versions of the ServiceNow Now Platform released prior to the Xanadu General Availability. Exploitation of this vulnerability can occur over the network without any privileges or user interaction, making it particularly dangerous.
