Description

Multiple files and folders in Utimaco SecurityServer 4.20.0.4 and 4.31.1.0. are installed with Read/Write permissions for authenticated users, which allows for binaries to be manipulated by non-administrator users. Additionally, entries are made to the PATH environment variable which, in conjunction with these weak permissions, could enable an attacker to perform a DLL hijacking attack.

Affected configurations

• utimaco block-safe firmware 2.0.0 • utimaco block-safe firmware 3.0.0 • utimaco cryptoserver cp5 firmware 5.0.0.0 • utimaco cryptoserver cp5 firmware 5.1.0.0 • utimaco cryptoserver cp5 vs-nfd firmware 5.1.0.0 • utimaco paymentserver firmware (>= 3.0 <= 4.31.0) • utimaco paymentserver hybrid firmware (>= 3.0 <= 4.33.0) • utimaco securityserver firmware (>= 3.0 <= 4.31.1)
