CVE-2022-24082
Published: 19 July 2022
Summary
CVE-2022-24082 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Pega Infinity. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 2.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2022-24082 affects on-premise installations of the Pega Platform when the JMX interface port is exposed to the Internet without proper port filtering. The flaw stems from unsafe handling of serialized data (CWE-502), enabling remote attackers to supply malicious payloads that target the underlying system. It carries a CVSS 3.1 score of 9.8 and does not impact PegaCloud deployments due to architectural differences.
An unauthenticated attacker with network access can exploit the exposed JMX port to upload crafted serialized objects, resulting in remote code execution with full system compromise potential. No user interaction or credentials are required, making the vector particularly severe for any internet-facing on-premise instance.
Pega’s security advisory B22 supplies a hotfix matrix for affected versions, while public proof-of-concept code targeting version 8.7.3 has been published on Packet Storm. Administrators are advised to restrict JMX port exposure and apply the vendor-supplied fixes promptly.
The associated EPSS score of 0.4558, both current and peak, reflects substantial exploitation interest following disclosure.

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.
