Medium Nessus Plugin ID 70783


The remote Ubuntu host is missing a security-related patch.


It was discovered that maas-import-pxe-files incorrectly loaded configuration information from the current working directory. A local attacker could execute code as an administrator if maas-import-pxe-files were run from an attacker-controlled directory.

It was discovered that maas-import-pxe-files doesn't cryptographically verify downloaded content. An attacker could modify images without detection. (CVE-2013-1058).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected maas-cluster-controller package.
