SecPod Research Team has discovered two vulnerabilities in NetDecision, which can be exploited by malicious people to disclose potentially sensitive information and potentially compromise a vulnerable system.
1) A boundary error in the HTTP server when handling web requests can be exploited to cause a stack-based buffer overflow via an overly-long URL.
Successful exploitation of this vulnerability may allow execution of arbitrary code, but requires the web server to be enabled (disabled by default).
2) An error in the Traffic Grapher server when processing web requests can be exploited to disclose the source code of NetDecision script files (".nd") via a specially crafted GET header.
NOTE: Additionally, a weakness exists in the Dashboard server when handling web requests for non-existent resources, which may disclose the absolute path of the web directory.
The vulnerabilities are confirmed in version 4.5.1. Other versions may also be affected.
Solution: Update to version 4.6.1.
