SB2022030865 - Multiple vulnerabilities in Icinga Web 2

Description

This security bulletin contains information about 3 vulnerabilities.

1) Path traversal (CVE-ID: CVE-2022-24716)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:A/U:Green

The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to path traversal in static library file requests when handling unauthenticated requests for library files. A remote attacker can request crafted file paths to disclose sensitive information.

Exposed files may include local system files accessible to the web-server user, including configuration files containing database credentials.

2) Path traversal (CVE-ID: CVE-2022-24715)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Green

The vulnerability allows a remote user to execute arbitrary code.

The vulnerability exists due to path traversal in SSH resources configuration handling when processing SSH resource file paths. A remote user can create SSH resource files in unintended directories to execute arbitrary code.

Exploitation requires access to the configuration.

3) Improper access control (CVE-ID: CVE-2022-24714)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote user to disclose host-related information.

The vulnerability exists due to improper access control in role restrictions linked to decommissioned services when evaluating access based on service custom variables. A remote user can retain access to host-related objects after service objects are decommissioned to disclose host-related information.

Only installations of Icinga 2 with the IDO writer enabled are affected. This applies when a role implicitly permits access to hosts through access to at least one of their services.

Remediation

Install update from vendor's website.
