CVE-2025-49148ClipShare Server Allows Local Privilege Escalation via DLL Hijacking
High 7.3
In plain English
A high-severity uncontrolled search path in clip_share_server from thevindu-w. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 6% of all known vulnerabilities).
Official description
ClipShare is a lightweight and cross-platform tool for clipboard sharing. Prior to 3.8.5, ClipShare Server for Windows uses the default Windows DLL search order and loads system libraries like CRYPTBASE.dll and WindowsCodecs.dll from its own directory before the system path. A local, non-privileged user who can write to the folder containing clip_share.exe can place malicious DLLs there, leading to arbitrary code execution in the context of the server, and, if launched by an Administrator (or another elevated user), it results in a reliable local privilege escalation. This vulnerability is fixed in 3.8.5.
