CentOS Web Panel - RCE (CVE-2025-48703)

CVE-2025-48703 is a severe vulnerability in CentOS Web Panel (CWP) before version 0.9.8.1205 that allows unauthenticated remote code execution through shell metacharacters in the t_total parameter of a filemanager changePerm request. Attackers who know a valid non-root username can exploit this flaw to execute arbitrary commands on the server, potentially leading to full system compromise.

CrowdSec has been tracking this vulnerability and its exploits since 24th of September 2025.

Based on data from the CrowdSec network, nearly all observed exploitation of CVE-2025-48703 is fully opportunistic, with attackers indiscriminately scanning the entire internet. These attacks are automated and lack any form of target selection or reconnaissance. In addition, according to the CrowdSec network, attack volume against CVE-2025-48703 has dipped slightly compared to the previous week. Although still commonly targeted, the decline suggests a cooling-off period. Long-term relevance remains, but attention is waning.

Attackers exploit endpoints like /myuser/index.php?module=filemanager&acc=changePerm by sending crafted POST requests with malicious payloads in parameters such as t_total or fileName, often attempting to execute arbitrary commands or establish reverse shells.
