Executive Summary

This vulnerability (CVE-2025-67279) affects TIM Solution GmbH's TIM BPM Suite and TIM FLOW software versions before 9.1.2. It involves the use of a broken or risky cryptographic algorithm, specifically the application storing password hashes using the MD5 hashing algorithm, which is considered weak and insecure. This allows a remote attacker to potentially obtain password hashes and escalate privileges. [2]

Impact Analysis

The vulnerability can allow attackers to obtain password hashes protected by weak MD5 hashing, making it easier for them to crack passwords and escalate privileges within the application. This could lead to unauthorized access to user accounts and sensitive data, compromising the security of the system. [2]

Detection Guidance

Detection of this vulnerability involves identifying the presence of TIM BPM Suite or TIM FLOW versions prior to 9.1.2 and checking for password hashes stored using the MD5 algorithm. Since the application stores password hashes in MD5 format, you can inspect the database or configuration files for MD5 hashed passwords. Additionally, monitoring HTTP requests for suspicious activity related to privilege escalation attempts may help. Specific commands are not provided in the resources. [2]

Mitigation Strategies

Immediate mitigation steps include upgrading TIM BPM Suite and TIM FLOW to version 9.1.2 or later, as this version addresses the vulnerability. Additionally, follow security best practices such as those recommended by OWASP, including proper password storage (avoiding weak hashing algorithms like MD5), authorization controls, and SQL injection prevention. The vendor has announced remediation efforts, but independent verification is advised. [2, 1]
