- Details
-
Impact
The
isMailtransport in PHPMailer before 5.2.20 might allow remote attackers to pass extra parameters to themailcommand and consequently execute arbitrary code by leveraging improper interaction between theescapeshellargfunction and internal escaping performed in the mail function in PHP. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-10033.This issue really emphasises that it's worth avoiding the built-in PHP
mail()function entirely.Patches
Fixed in 5.2.20
Workarounds
Send via SMTP to localhost instead of calling the
mail()function.References
