Summary

CVE-2023-29443 is a medium-severity Improper Restriction of XML External Entity Reference (CWE-611) vulnerability in Zohocorp Manageengine Assetexplorer. Its CVSS base score is 4.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 14% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Zoho ManageEngine ServiceDesk Plus before version 14105, ServiceDesk Plus MSP before 14200, SupportCenter Plus before 14200, and AssetExplorer before 6989 contain an XML external entity vulnerability. The flaw resides in the Reports integration API endpoint, which processes XML responses from an attacker-controlled server without proper restrictions, allowing SDAdmin users to trigger XXE parsing.

An authenticated SDAdmin attacker can supply a crafted server endpoint that returns malformed XML, enabling the application to retrieve and expose sensitive internal files or resources over the network. The attack requires high privileges and targets confidentiality only, consistent with the CVSS 4.9 rating and CWE-611 classification.

Vendor advisories at https://www.manageengine.com/products/service-desk/CVE-2023-29443.html recommend upgrading the affected products to the fixed releases listed in the description to eliminate the vulnerable XML handling code.

The associated EPSS score has remained flat at 0.0583 with no material increase since disclosure.
