## Technical details

A remote command execution (RCE) vulnerability exists in multiple H3C networking products due to improper neutralization of special elements in the 'sessionid' parameter (CWE-77). An unauthenticated attacker can exploit this by sending a crafted POST request to the device's management interface. This allows the attacker to bypass authentication and execute arbitrary commands on the underlying operating system. The vulnerability affects ERG3, ERG5, UR, and XiaoBei series routers, as well as specific MSG, USG, UAP, and WAP models. H3C has released firmware version Release 0162P11 to address this issue for the ERG3 and UR series; users are advised to upgrade or disable remote Web and Telnet management as a temporary mitigation.
