CVE-2024-25699: Portal for ArcGIS has an invalid authentication vulnerability

Noroxi assessment

Priority: Monitor (action score 34/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.69% (FIRST EPSS); higher than 52.6% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

There is a difficult‑to‑exploit improper authentication issue in the Home application for Esri Portal for ArcGIS versions 11.2 and below on Windows and Linux, and ArcGIS Enterprise versions 11.1 and below on Kubernetes, which under unique circumstances could allow a remote, authenticated attacker with low‑privileged access to compromise the confidentiality, integrity, and availability of the software. Successful exploitation allows the attacker to cross an authentication and authorization boundary beyond their originally assigned access, resulting in a scope change.

Weakness class (CWE)

CWE-287 · Improper Authentication

CVSS vector

CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H

nvd-primary

Root cause

Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.
