CVE-2025-64067 — Authorization Bypass Through User-Controlled Key (IDOR) in Primakon Project Contract Management

Primakon Pi Portal 1.0.18 API endpoints responsible for retrieving object-specific or filtered data (e.g., user profiles, project records) fail to implement sufficient server-side validation to confirm that the requesting user is authorized to access the requested object or dataset. This vulnerability can be exploited in two ways: Direct ID manipulation and IDOR, by changing an ID parameter (e.g., user_id, project_id) in the request, an attacker can access the object and data belonging to another user; and filter Omission, by omitting the filtering parameter entirely, an attacker can cause the endpoint to return an entire unfiltered dataset of all stored records for all users. This flaw leads to the unauthorized exposure of sensitive personal and organizational information.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.2% (30-day exploitation probability)+2
Technical severity (medium)+3
Automatable exploitation (SSVC)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Primakon Project Contract Management).
The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
