A extreme safety vulnerability existed within the id administration system FreeIPA that will expose person credentials. Exploiting the vulnerability may permit an adversary to entry delicate information.
FreeIPA System Vulnerability
Safety researcher Egor Dimitrenko from PT Swarm found a extreme vulnerability in Free IPA that will permit exterior entity XML exterior entity (XXE) assaults.
FreeIPA is an open-source id administration system from Crimson Hat. It presents Free Id, Coverage, and Audit (IPA) options for Linux, Unix, Home windows, and macOS methods.
In accordance with Crimson Hat’s advisory, the vulnerability existed within the pki-core package deal, resulting in XXE assaults. As acknowledged,
A flaw was present in pki-core. Entry to exterior entities when parsing XML paperwork can result in XML exterior entity (XXE) assaults.
This vulnerability, CVE-2022-2414, obtained an important-severity ranking with a CVSS rating of seven.5. An adversary may exploit the bug to entry arbitrary recordsdata by sending maliciously crafted HTTP requests.
In worst-case exploitations, such XXE assaults may additionally permit distant code execution.
Crimson Hat confirmed that this vulnerability impacts Crimson Hat Enterprise Linux (RHEL) variations 6 to 10. Additionally, the flaw has no mitigations or workarounds. Nonetheless, they’ve shortly addressed the difficulty, releasing the patch with the up to date pki-core packages for RHEL to 10, whereas RHEL 6 is out of scope.
Commenting extra concerning the bug, Dimitrenko informed The Every day Swig that exploiting the bug is trivial because it requires no credentials. As a substitute, an adversary merely wants an “accessible endpoint” to set off the exploit.
In addition to, elaborating on the susceptible part DogTag – the certification system, the researcher stated,
DogTag can be utilized as a PKI service for any mission, but it surely’s properly generally known as part of FreeIPA system. Since DogTag is built-in into FreeIPA, FreeIPA is susceptible if nonetheless unpatched.
Furthermore, the researcher defined that real-world exploits of this problem may permit an attacker to learn the Listing Supervisor password from the FreeIPA config. Thus, the attacker may take management of your entire focused infrastructure.
🐳 Crimson Hat mounted an Unauth XXE (CVE-2022-2414) in FreeIPA discovered by our researcher @elk0kc.
In some instances, it permits attackers to learn the Listing Supervisor password from the config of FreeIPA and take full management of the infrastructure.
