Several security issues were fixed in PostfixAdmin.

Summary

Several security issues were fixed in PostfixAdmin.

Software Description:

- postfixadmin: Virtual mail hosting interface for Postfix

Details:

It was discovered that Smarty, that is integrated in the PostfixAdmin

code, was not properly sanitizing user input when generating templates. An

attacker could, through PHP injection, possibly use this issue to execute

arbitrary code. (CVE-2022-29221)

It was discovered that Moment.js, that is integrated in the PostfixAdmin

code, was using an inefficient parsing algorithm when processing date

strings in the RFC 2822 standard. An attacker could possibly use this

issue to cause a denial of service. (CVE-2022-31129)

It was discovered that Smarty, that is integrated in the PostfixAdmin

code, was not properly escaping JavaScript code. An attacker could

possibly use this issue to conduct cross-site scripting attacks (XSS).
