CVE-2019-15983 (GCVE-0-2019-15983)

Vulnerability from cvelistv5 – Published: 2020-01-06 07:45 – Updated: 2024-11-15 17:51

Title

Cisco Data Center Network Manager XML External Entity Read Access Vulnerability

Summary

A vulnerability in the SOAP API of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker to gain read access to information that is stored on an affected system. To exploit this vulnerability, an attacker would need administrative privileges on the DCNM application. The vulnerability exists because the SOAP API improperly handles XML External Entity (XXE) entries when parsing certain XML files. An attacker could exploit this vulnerability by inserting malicious XML content in an API request. A successful exploit could allow the attacker to read arbitrary files from the affected device. Note: The severity of this vulnerability is aggravated by the vulnerabilities described in the Cisco Data Center Network Manager Authentication Bypass Vulnerabilities advisory, published simultaneously with this one.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
