[2.1.0] Checkmk Werk 16198 created: mk_informix: Do not allow privilege escalation

by Checkmk werks level 1

Title: mk_informix: Do not allow privilege escalation Class: security Compatible: compat Component: checks Date: 1709909870 Edition: cre Level: 1 Version: 2.1.0p41 The informix database monitoring plugin would previously <code>eval</code> statements parsed from <code>$INFORMIXDIR/bin/onstat</code>. Since the plugin is usually run as root, this could cause statements injected in <code>$INFORMIXDIR/bin/onstat</code> to be run as root as well. By adding scripts named the same as other functionality found in <code>$PATH</code> to <code>$INFORMIXDIR/bin</code>, <code>$PATH</code> functionality could also be overshadowed and the custom executed as root. Finally, <code>$INFORMIXDIR/bin/onstat</code> would be executed as root, allowing a substituted script to be run with elevated privileges. With this werk, the environment variables will be exported instead and <code>$PATH</code> will now be searched before <code>$INFORMIXDIR/bin</code>. The plugin will now also check if <code>$INFORMIXDIR/bin/onstat</code> belongs to root if the plugin is executed as root. If not, it will be executed as the user owning the executable. This issue was found during internal review. <em>Affected Versions</em>: LI: 2.3.0 (beta) LI: 2.2.0 LI: 2.1.0 LI: 2.0.0 (EOL) <em>Vulnerability Management</em>: We have rated the issue with a CVSS Score of 8.8 (High) with the following CVSS vector: <code>CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H</code> and assigned CVE <code>CVE-2024-28824</code>.

[2.1.0] Checkmk Werk 16232 created: mk_oracle(ps1): Prevent privilege esclation to root

by Checkmk werks level 1

Title: mk_oracle(ps1): Prevent privilege esclation to root Class: security Compatible: compat Component: checks Date: 1705479643 Edition: cre Level: 3 Version: 2.1.0p41 The agent plugins mk_oracle, mk_oracle.ps1 and mk_oracle_crs were vulnerable to privilege escalation to root by the oracle user. A malicious oracle user could replace a binary (e.g. sqlplus) with another script and put it in the corresponding directory. The script would be executed by the root user. All binaries, which are called by the plugins, are now checked if they need to be executed as a non-root (non-administrator under Windows) user, preventing the privilege escalation. Affected binaries are: sqlplus, tnsping, crsctl. <h3>Affected Versions</h3> LI: 2.3.0 (beta) LI: 2.2.0 LI: 2.1.0 LI: 2.0.0 (EOL) and older <h3>Mitigations</h3> If updating is not possible, disable the mk_oracle plugin. <h3>Vulnerability Management</h3> We have rated the issue with a CVSS score of 8.2 (High) with the following CVSS vector: <code>CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H</code> We have assigned <code>CVE-2024-0638</code>. <h3>Changes</h3> All called binaries are now executed in a safe way.
