CVE-2023-49442
CWE-502Published: January 3, 2024· Updated: Jun 17, 2026
Official Description
Deserialization of Untrusted Data in jeecgFormDemoController in JEECG 4.0 and earlier allows attackers to run arbitrary code via crafted POST request.
Risk Analysis
JEECG 4.0 and earlier are vulnerable to insecure deserialization, allowing remote attackers to execute arbitrary code via crafted POST requests. This critical vulnerability has a CVSS score of 9.8, reflecting the potential for full system compromise. It is a high-priority security issue.
No public exploit is known, and the vulnerability is not in the CISA KEV. The flaw is remotely exploitable with low complexity.
Upgrade to a version of JEECG that is not affected by this deserialization flaw. Avoid deserializing untrusted data.
Technical Analysis
CVE-2023-49442 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
