Deeper analysis AI-assisted summary

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

Arcserve UDP versions prior to 5.0 Update 4 are affected by a directory traversal vulnerability tracked as CVE-2015-4068 and CWE-22. The flaw resides in the reportFileServlet and exportServlet servlets and allows access to arbitrary file paths supplied by an attacker.

Unauthenticated remote attackers can exploit the issue over the network by submitting crafted paths to these servlets, resulting in disclosure of sensitive information or a denial-of-service condition. The vulnerability carries a CVSS 3.1 base score of 9.1 reflecting network attack vector, low complexity, and high impact to confidentiality and availability.

Vendor documentation for Arcserve UDP 5.0 Update 4 states that the release resolves the directory traversal issue, and users are advised to apply the update. Corresponding Zero Day Initiative advisories ZDI-15-241 and ZDI-15-242 provide additional technical context on the affected servlets.

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.

SI-10 Information Input Validation
addresses: CWE-22

Validates pathnames and filenames to prevent traversal outside intended directories.

PR.PS-02 partial match

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
blocks

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