VAR-200505-0164
Vulnerability from variot - Updated: 2023-12-18 13:50Smc.exe in My Firewall Plus 5.0 build 1117, and possibly other versions, does not drop privileges before launching the Log Viewer export functionality, which allows local users to corrupt arbitrary files by saving log files. A local insecure file creation vulnerability affects Webroot My Firewall. This issue is due to an access validation issue that allows an unprivileged user to create files with escalated privileges. This issue may be exploited by a local attacker to corrupt arbitrary files on an affected computer with SYSTEM privileges.

TITLE: My Firewall Plus Arbitrary File Corruption Vulnerability
SECUNIA ADVISORY ID: SA13577
VERIFY ADVISORY: http://secunia.com/advisories/13577/
CRITICAL: Not critical
IMPACT: Manipulation of data, DoS
WHERE: Local system
SOFTWARE: My Firewall Plus 5.x http://secunia.com/product/4276/
DESCRIPTION: Secunia Research has discovered a vulnerability in My Firewall Plus, which can be exploited by malicious, local users to manipulate the content of arbitrary files on a vulnerable system.
Successful exploitation requires that the user has access to the Log Viewer (all users by default).
The vulnerability has been confirmed in version 5.0 (build 1117). Other versions may also be affected.
NOTE: This vulnerability has been rated "Not critical" as only trusted users should have access to the configuration and logging functionality.
SOLUTION: Update to version 5.0 (build 1119) or apply patch.
Patch: http://www.webroot.com/services/mfp_patch.exe
Use the "Password Protection" feature to restrict access to the configuration and logging functionality.
PROVIDED AND/OR DISCOVERED BY: Carsten Eiram, Secunia Research.
