{"id":"AZL-37158","summary":"CVE-2018-19518 affecting package uw-imap 2007f-26","details":"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OS commands if the IMAP server name is untrusted input (e.g., entered by a user of a web application) and if rsh has been replaced by a program with different argument semantics. For example, if rsh is a link to ssh (as seen on Debian and Ubuntu systems), then the attack can use an IMAP server name containing a \"-oProxyCommand\" argument.","modified":"2026-04-01T05:12:28.142689Z","published":"2018-11-25T10:29:00Z","upstream":["CVE-2018-19518"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-19518"}],"affected":[{"package":{"name":"uw-imap","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/uw-imap"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2007f-26"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-37158.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
