Discussion
ClearBudget Local File Include and Authentication Bypass Vulnerabilities
ClearBudget is prone to a local file-include vulnerability and an authentication-bypass vulnerability.
An attacker can exploit the local file-include vulnerability using directory-traversal strings to view local files and execute local scripts within the context of the webserver process. A successful attack can allow the attacker to obtain sensitive information or gain unauthorized access to an affected computer in the context of the vulnerable server.
The attacker can exploit the authentication-bypass vulnerability to gain unauthorized access to the affected application.
ClearBudget 0.6.1 is vulnerable; other versions may also be affected.
