CVE-2026-33613Network attack vector

Code execution via generateSrpArray command injection

Published Apr 2, 2026 · Updated Apr 2, 2026

OS command injection in MB connect line mbCONNECT24 and mymbCONNECT24 2.19.4 and earlier allows attackers to execute code remotely. The generateSrpArray function incorporates data from the user table into an operating system command without neutralizing shell metacharacters. Exploitation requires another capability that writes arbitrary data to the user table, after which injected commands can fully compromise the portal host.
