CVE-2018-9846

HIGH

Roundcube Webmail 1.2.0-1.3.5 - IMAP Injection via Archive Plugin _uid Parameter

Title source: llm
STIX 2.1

Description

In Roundcube from versions 1.2.0 to 1.3.5, with the archive plugin enabled and configured, it's possible to exploit the unsanitized, user-controlled "_uid" parameter (in an archive.php _task=mail&_mbox=INBOX&_action=plugin.move2archive request) to perform an MX (IMAP) injection attack by placing an IMAP command after a %0d%0a sequence. NOTE: this is less easily exploitable in 1.3.4 and later because of a Same Origin Policy protection mechanism.
