Description

A format string vulnerability was found in the Internal Backup on the ADM. The vulnerability occurs because user-controlled task input may be included in an error response and processed through an unsafe format string operation. An authenticated attacker can exploit this issue to disclose memory information or cause denial of service of the affected CGI process. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RUN1 as well as from ADM 5.0.0 through ADM 5.1.3.RI81.
