SUSE update for SUSE Manager Client Tools Beta

1) Symlink attack

EUVDB-ID: #VU1344

Risk: Low

CVSSv3.1: 7.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2016-9566

CWE-ID: CWE-61 - UNIX Symbolic Link (Symlink) Following

Exploit availability: Yes

Description

The vulnerability allows a local user obtain elevated privileges on vulnerable system.

The vulnerability exists due to the application handles log files in unsafe manner. A local user with access to Nagios application (nagios account or member of nagios group) can cerate a specially crafted symlink to nagios log file and execute arbitrary command on vulnerable system with root privileges.

Successful exploitation of this vulnerability may allow a local user to obtain full access to vulnerable system.

Mitigation

Update the affected package SUSE Manager Client Tools Beta to the latest version.

2) UNIX symbolic link following

EUVDB-ID: #VU68336

Risk: Low

CVSSv3.1: 6.1 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-3698

CWE-ID: CWE-61 - UNIX Symbolic Link (Symlink) Following

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a symlink following issue in the cronjob shipped with nagios. A local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.

Successful exploitation of this vulnerability may result in privilege escalation.

Mitigation

Update the affected package SUSE Manager Client Tools Beta to the latest version.
