Heap-based buffer overflow in the Visionsoft Audit on Demand Service (VSAOD) in Visionsoft Audit 12.4.0.0 allows remote attackers to cause a denial of service (persistent daemon crashes) or execute arbitrary code via a long filename in a "LOG." command.

The Visionsoft Audit on Demand Service (VSAOD) in Visionsoft Audit 12.4.0.0 does not require authentication for (1) the "LOG." command, which allows remote attackers to create or overwrite arbitrary files; (2) the SETTINGSFILE command, which allows remote attackers to overwrite the ini file, and reconfigure VSAOD or cause a denial of service; or (3) the UNINSTALL command, which allows remote attackers to cause a denial of service (daemon shutdown). NOTE: vector 1 can be leveraged for code execution by writing to a Startup folder.

The Visionsoft Audit on Demand Service (VSAOD) in Visionsoft Audit 12.4.0.0 uses weak cryptography (XOR) when (1) transmitting passwords, which allows remote attackers to obtain sensitive information by sniffing the network; and (2) storing passwords in the configuration file, which allows local users to obtain sensitive information by reading this file.

The Visionsoft Audit on Demand Service (VSAOD) in Visionsoft Audit 12.4.0.0 allows remote attackers to obtain sensitive information via (1) a LOG.ON command, which reveals the logging pathname in the server response; (2) a VER command, which reveals the version number in the server response; and (3) a connection, which reveals the version number in the banner.

The Visionsoft Audit on Demand Service (VSAOD) in Visionsoft Audit 12.4.0.0 allows remote attackers to conduct replay attacks by capturing and resending data from the DETAILS and PROCESS sections of a session that schedules an audit.
