CVE ID:
Rule Protection Details
Description: University of Washington IMAP Toolkit 2007f on UNIX, as used in imap_open() in PHP and other products, launches an rsh command (by means of the imap_rimap function in c-client/imap4r1.c and the tcp_aopen function in osdep/unix/tcp_unix.c) without preventing argument injection, which might allow remote attackers to execute arbitrary OS commands if the IMAP server name is untrusted input (e.g., entered by a user of a web application) and if rsh has been replaced by a program with different argument semantics.
Impact: An attacker can execute arbitrary code via a successful exploit in the context of the vulnerable software.
Affected OS: Windows, Linux, Others
