Description:
Sowhat has reported two vulnerabilities and a weakness in Active Webcam, which can be exploited by malicious people to cause a DoS (Denial of Service) and detect the presence of local files.
1) An input validation error can be exploited to cause a vulnerable server to become unaccessible by requesting a specially crafted file.
Example:
http://[victim]:8080/A:\a.txt
The vulnerability has been confirmed in version 5.5. Other versions may also be affected.
2) Different error messages are returned to users depending on whether a given file exists or not. This can be exploited to detect the presence of local files.
Example:
http://[victim]:8080/c:\test.txt
It is also possible to disclose the full installation path by requesting a non-existing file.
The weakness has been confirmed in version 5.5. Other versions may also be affected.
3) An error in the HTTP communication handling can be exploited to crash a vulnerable service by sending a large amount of HTTP requests (more than 1000).
The vulnerability has been reported in version 5.5. Other versions may also be affected.
