Summary

CVE-2020-15505 is a critical-severity Use of Incorrectly-Resolved Name or Reference (CWE-706) vulnerability in Mobileiron Core. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 0.0% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2020-15505 is a remote code execution vulnerability affecting MobileIron Core and Connector versions 10.3.0.3 and earlier along with multiple 10.4.x, 10.5.x, and 10.6.0.0 releases; Sentry versions 9.7.2 and earlier plus 9.8.0; and Monitor and Reporting Database (RDB) version 2.0.0.1 and earlier. The flaw carries a CVSS score of 9.8 and is associated with CWE-706, enabling remote attackers to execute arbitrary code through unspecified vectors that reference materials indicate involve Hessian-based Java deserialization.

Unauthenticated attackers with network access can exploit the issue without user interaction to achieve full remote code execution on affected MobileIron components, potentially compromising device management, authentication, and reporting functions in enterprise mobile deployments.

MobileIron advisory information states that security updates are available to address the vulnerability in the listed products. Public references also include exploit code demonstrating the deserialization path, indicating active researcher interest shortly after disclosure.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires timely installation of security updates that MobileIron states are available to eliminate the deserialization RCE flaw.

prevent

Mandates validation of all input, which would block the malicious Hessian-serialized objects used to achieve unauthenticated code execution.

preventdetect

Requires mechanisms to detect and block malicious code payloads delivered via the deserialization vector before or during execution.
