What is CVE-2025-55763?
The buffer overflow vulnerability present in the URI parser of CivetWeb versions 1.14 through 1.16 allows an attacker to conduct remote code execution via a specially crafted HTTP request. This exploit occurs during the processing of requests and can lead to corruption of heap memory. Consequently, this may enable unauthorized access and control over the server, causing potential service disruptions and unauthorized command execution.
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
