EUVDB-ID: #VU35769

Risk: High

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

CVE-ID: CVE-2019-13024

CWE-ID: CWE-77 - Command injection

Exploit availability: Yes

Description

The vulnerability allows a remote authenticated user to execute arbitrary code.

Centreon 18.x before 18.10.6, 19.x before 19.04.3, and Centreon web before 2.8.29 allows the attacker to execute arbitrary system commands by using the value "init_script"-"Monitoring Engine Binary" in main.get.php to insert a arbitrary command into the database, and execute it by calling the vulnerable page www/include/configuration/configGenerate/xml/generateFiles.php (which passes the inserted value to the database to shell_exec without sanitizing it, allowing one to execute system arbitrary commands).

Mitigation

Install update from vendor's website.
