Summary

CVE-2015-0666 is a high-severity Path Traversal (CWE-22) vulnerability in Cisco Prime Data Center Network Manager. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities 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.

CVE-2015-0666 is a directory traversal vulnerability, tracked as Bug ID CSCus00241 and assigned CWE-22, that affects the fmserver servlet in Cisco Prime Data Center Network Manager (DCNM) versions prior to 7.1(1). The flaw permits remote attackers to supply a crafted pathname and retrieve arbitrary files from the underlying system, resulting in a CVSS 3.1 base score of 7.5 with network attack vector, low complexity, and no required privileges or user interaction.

Unauthenticated attackers with network access can exploit the servlet directly to read sensitive files, achieving high confidentiality impact without affecting integrity or availability. The vulnerability can be reached over the network without authentication, enabling straightforward remote file disclosure.

Cisco Security Advisory cisco-sa-20150401-dcnm and associated vendor notices recommend upgrading affected DCNM installations to version 7.1(1) or later to address the issue. The vulnerability is listed in CISA's Known Exploited Vulnerabilities catalog, confirming observed real-world exploitation.

Likely Mitigating Controls AI

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.

addresses: CWE-22

Validates pathnames and filenames to prevent traversal outside intended directories.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
