CVE-2026-54211

Name of the Vulnerable Software and Affected Versions TeamDavid versions prior to Rollout 525

Description The Webbox application contains a buffer overflow issue in the "//serverClient close.html" endpoint. An authenticated attacker can cause a server crash and denial of service by submitting excessively long values in multiple form data parameters. If the stack state allows or a stack canary is disclosed, this could lead to remote code execution and full server compromise. A stack canary is a security value placed in memory to detect buffer overflows before they can be exploited.

Recommendations Update TeamDavid to a version later than Rollout 524. Restrict access to the "//serverClient close.html" endpoint to minimize the risk of exploitation.
