Debian DLA-2198-1 : otrs2 security update

high Nessus Plugin ID 136288

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities have been discovered in otrs2 (Open source Ticket Request System)

CVE-2020-1770

Support bundle generated files could contain sensitive information that might be unwanted to be disclosed.

CVE-2020-1772

It’s possible to craft Lost Password requests with wildcards in the Token value, which allows attacker to retrieve valid Token(s), generated by users which already requested new passwords.

CVE-2020-1774

When user downloads PGP or S/MIME keys/certificates, exported file has same name for private and public keys. Therefore it’s possible to mix them and to send private key to the third-party instead of public key.

For Debian 8 'Jessie', these problems have been fixed in version 3.3.18-1+deb8u15.

We recommend that you upgrade your otrs2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected otrs, and otrs2 packages.
