Title: 4D WebStar Tomcat Plugin Remote Buffer Overflow Vulnerability
Severity: HIGH
Description:
4D WebStar is an application providing web, FTP and email services for Apple Mac OS X.
The Tomcat Plugin supplied with the HTTP server is reportedly prone to a remote buffer overflow vulnerability. This issue arises because the application fails to perform boundary checks prior to copying user-supplied data into sensitive process buffers.
Specifically, this issue presents itself when the application handles a long URI request. Reportedly, this can cause memory corruption as data is copied into a finite sized buffer. A successful attack can result in a crash or arbitrary code execution allowing the attacker to gain unauthorized access to the affected computer.
The Tomcat Plugin is enabled by default.
4D WebStar 5.3.3 and 5.4 were reported to be vulnerable.
Affected Products:
- 4D WebSTAR 5.3.3
- 4D WebSTAR 5.4.0
