Executive brief
Redeight CMS, a content management system, uses an outdated and insecure method for storing user passwords. Because the system uses the MD5 algorithm without additional security measures like salting, an attacker who gains access to the database can easily convert the stored data back into plain-text passwords. This could lead to full account takeovers and the exposure of sensitive user credentials.
Technical details
Redeight CMS version 1.0 is vulnerable to weak password encoding (CWE-261). The application utilizes the MD5 hashing algorithm without a salt to store user credentials in the database. MD5 is considered cryptographically broken due to collision vulnerabilities and high computation speeds. An attacker who obtains the password hashes (e.g., through a database leak or SQL injection) can use rainbow tables or brute-force attacks to recover the original plaintext passwords with minimal effort. The vulnerability was identified by CERT.PL and assigned a CVSS 4.0 base score of 5.9.
