CVE-2025-0670: Akinsoft ProKuafor Auth Bypass Vulnerability

CVE-2025-0670 Overview

CVE-2025-0670 is an authorization bypass vulnerability in Akinsoft ProKuafor, a salon management application. The flaw is classified under [CWE-639] Authorization Bypass Through User-Controlled Key, also known as Insecure Direct Object Reference (IDOR). An authenticated attacker can manipulate user-controlled key parameters to access resources belonging to other tenants or users, leading to resource leak exposure. The issue affects ProKuafor versions from s1.02.07 before v1.02.08. The vulnerability was disclosed through Turkey's National Cyber Incident Response Center (USOM) advisory TR-25-0204.

Critical Impact
Authenticated attackers can bypass authorization checks by modifying object identifiers in requests, exposing resources and data belonging to other users of the ProKuafor application.

Affected Products

Akinsoft ProKuafor version s1.02.07
Akinsoft ProKuafor versions prior to v1.02.08
Deployments of ProKuafor that expose the application to networked users

Technical Details for CVE-2025-0670

Vulnerability Analysis

The vulnerability arises from ProKuafor accepting user-supplied identifiers to retrieve or manipulate resources without validating that the requesting user owns or has permission to access the referenced object. This pattern, tracked under [CWE-639], allows an authenticated user to substitute another entity's identifier and receive that entity's data. The result is a resource leak exposure where confidential records may cross authorization boundaries. Exploitation requires network access and valid, high-privilege credentials, and does not require user interaction. Impact spans confidentiality, integrity, and availability at a limited scope.

Root Cause

The application relies on client-supplied keys, such as record identifiers or object references, to fetch data without performing server-side ownership checks. When authorization decisions are anchored to a user-controllable value rather than the authenticated session context, an attacker can enumerate or guess identifiers to retrieve unauthorized objects.

Attack Vector

An authenticated attacker interacts with ProKuafor over the network and modifies parameters in application requests, such as query strings, POST body fields, or path segments containing numeric or predictable identifiers. By iterating through valid identifier ranges, the attacker retrieves resources belonging to other accounts. No specialized tooling is required beyond an HTTP client or a proxy such as Burp Suite. Refer to the USOM Notification TR-25-0204 for vendor-coordinated disclosure details.

Detection Methods for CVE-2025-0670

Indicators of Compromise

Sequential or non-sequential enumeration of resource identifiers in ProKuafor request logs from a single authenticated session
Successful HTTP 200 responses to requests referencing identifiers that fall outside the requesting user's normal tenant scope
Unusual volumes of read requests to record-retrieval endpoints from a single account within a short time window

Detection Strategies

Baseline normal per-user access patterns for ProKuafor endpoints and alert on deviations that suggest cross-tenant object access
Inspect application access logs for identifier parameters that do not correlate with the session's owning account
Correlate authentication events with subsequent object-access requests to detect sessions accessing anomalously broad identifier ranges

Monitoring Recommendations

Forward ProKuafor web server and application logs to a central log platform and retain them for post-incident review
Monitor for spikes in authorization-relevant HTTP status codes such as 200 on record-fetch endpoints when accessed by low-trust accounts
Track failed and successful requests per authenticated user against object-retrieval endpoints, and alert on outliers

How to Mitigate CVE-2025-0670

Immediate Actions Required

Upgrade ProKuafor to version v1.02.08 or later, which contains the vendor fix
Audit application accounts and revoke unused or excessive privileges, since exploitation requires authenticated access
Review recent access logs for signs of identifier enumeration or cross-account data retrieval

Patch Information

Akinsoft released a fixed build in ProKuafor v1.02.08. All versions from s1.02.07 up to but not including v1.02.08 remain vulnerable. Coordinated disclosure was tracked through the Siber Güvenlik Notification TR-25-0204 and the USOM Notification TR-25-0204. Administrators should validate the installed build number after patching.

Workarounds

Restrict network access to the ProKuafor application using firewall rules or VPN gating until the patch is applied
Enforce least-privilege on ProKuafor accounts to reduce the pool of users capable of triggering the flaw
Place a reverse proxy or web application firewall in front of ProKuafor to alert on and rate-limit identifier enumeration patterns

bash

# Example: restrict inbound access to the ProKuafor host until patched
# Replace <TRUSTED_CIDR> with your administrative network range
iptables -A INPUT -p tcp --dport 80 -s <TRUSTED_CIDR> -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -s <TRUSTED_CIDR> -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
