CVE-2022-22957
Published: 13 April 2022
Summary
CVE-2022-22957 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Vmware Identity Manager. Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 2.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
VMware Workspace ONE Access, Identity Manager, and vRealize Automation contain a remote code execution vulnerability tracked as CVE-2022-22957. The flaw arises from unsafe deserialization of untrusted data (CWE-502) that can be triggered through a malicious JDBC URI, and it is one of two related issues disclosed together with CVE-2022-22958. It received a CVSS 3.1 score of 7.2 reflecting network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability.
An attacker must possess administrative privileges to supply the crafted JDBC URI and thereby execute arbitrary code on the affected server. Successful exploitation grants the actor full control over the application process and any data or services reachable from it.
VMware’s advisory VMSA-2022-0011 addresses remediation steps for the affected products. Public exploit code for the issue has been posted on Packet Storm, and the vulnerability’s EPSS score reached a peak of 0.4726 with a current value of 0.4323.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
