Overview
The Common Vulnerabilities and Exposures (CVE) system has recently identified a significant flaw in the UnoPim open-source Product Information Management (PIM) system. This vulnerability, designated as CVE-2025-55743, can potentially lead to a system compromise or data leakage, impacting any organization that uses versions of UnoPim prior to 0.2.1. This vulnerability is of particular importance due to the broad use of UnoPim and the severity of its potential impact.
Vulnerability Summary
CVE ID: CVE-2025-55743
Severity: High (8.8 CVSS Score)
Attack Vector: Network
Privileges Required: Low
User Interaction: Required
Impact: System compromise or data leakage
Affected Products
A new way to communicate
Ameeba Chat is built on encrypted identity, not personal profiles.
Message, call, share files, and coordinate with identities kept separate.
- • Encrypted identity
- • Ameeba Chat authenticates access
- • Aliases and categories
- • End-to-end encrypted chat, calls, and files
- • Secure notes for sensitive information
Private communication, rethought.
Product | Affected Versions
UnoPim | Before 0.2.1
How the Exploit Works
The vulnerability stems from UnoPim’s image upload feature at the user creation stage. The system only performs client-side file type validation. This allows an attacker to upload an image, capture the request through a Proxy like Burp suite, and make changes to the file extension and content. With this exploit, an attacker can potentially compromise the system or leak data.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited using a manipulated HTTP request:
POST /user/create HTTP/1.1
Host: target.example.com
Content-Type: image/jpeg
{ "image_file": "malicious_payload.jpg" }In the above example, an attacker could replace “malicious_payload.jpg” with a file containing malicious code. The UnoPim system would accept this as a valid image file due to the client-side validation, and the malicious code could then execute within the system leading to potential compromise.
Mitigation
Users are strongly advised to apply the vendor patch and upgrade to version 0.2.1 or later. In the interim, users can also employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. However, these should be considered as short-term solutions, and updating the software should be a priority to prevent potential exploitation of the vulnerability.
