CVE-2023-26058 — An XXE issue was discovered in Nokia NetAct before 22 FP2211 via an XML document to a Performance Manager page

Medium CVSS 6.5

An XXE issue was discovered in Nokia NetAct before 22 FP2211 via an XML document to a Performance Manager page. Input validation and a proper XML parser configuration are missing. For an external attacker, it is very difficult to exploit this, because a few dynamically created parameters such as Jsession-id, a CSRF token, and an Nxsrf token would be needed. The attack can realistically only be performed by an internal user.

Matched remediation archetype

XML external entity and unsafe XML processing

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory XML parsers used by APIs, file imports, office or image formats, identity protocols, feeds, and background jobs.
  • Determine whether document type declarations, external entities, XInclude, schemas, or network resolvers are enabled.
  • Map parser filesystem and network access and the sensitivity of documents it processes.

Remediate safely

  • Configure each parser to reject document type declarations and disable external entity, XInclude, and network resolution features.
  • Prefer a data format or hardened parser that does not support external resolution, and apply input size and depth limits.
  • Update affected XML libraries and centralize secure parser construction so callers cannot silently override it.
