AIX (IJ50433)

medium Nessus Plugin ID 195314

Language:

Synopsis

The remote AIX host is missing a security patch.

Description

The version of AIX installed on the remote host is prior to APAR IJ50433. It is, therefore, affected by a vulnerability as referenced in the IJ50433 advisory.

 - sendmail through 8.17.2 allows SMTP smuggling in certain configurations. Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because sendmail supports <LF>.<CR><LF> but some other popular e-mail servers do not. This is resolved in 8.18 and later versions with 'o' in srv_features.
 (CVE-2023-51765)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Please apply the appropriate interim fix per APAR IJ50433.
