Title: Mozilla Firefox Download Manager World Writable File Local Privilege Escalation Vulnerability
Severity: MODERATE
Description:
Mozilla Firefox is a web browser available for multiple operating systems.
A local privilege-escalation vulnerability occurs because the browser uses predictable names when downloading and saving files to the downloads folder. This issue occurs when choosing the 'open with' option. Specifically, a local attacker can create a malicious file, give it the name of a file that already resides in '/tmp', and then replace that file with the malicious file. This file would then appear in the download manager and can be automatically opened by Firefox.
The attacker must know the name of a file that the victim intends to open with Download Manager. The malicious file would run in the context of the victim running the affected browser.
NOTE: This issue was previously covered in BID 36843 (Mozilla Firefox and SeaMonkey MFSA 2009-52 through -64 Multiple Vulnerabilities), but has been assigned its own record to better document it.
