Description:
Stefan Esser has reported two vulnerabilities in Cacti, which can be exploited by malicious people to bypass certain security restrictions and compromise a vulnerable system.
1) Input passed to the "no_http_headers" parameter isn't properly verified before being used. This can be exploited to overwrite session structures and bypass certain filtering mechanisms.
Successful exploitation allows people to gain administrative privileges and perform various SQL injection attacks, but requires that "register_globals" is enabled.
2) An error in the administrative interface can be exploited to inject arbitrary shell commands by manipulating the path to "rrdtool".
Successful exploitation requires administrative privileges.
The vulnerabilities have been reported in version 0.8.6e and prior.
Solution:
Update to version 0.8.6f.
