CVE-2024-53356: Easyvirt CO2SCOPE

Critical severity, CVSS 9.8. EPSS: 0.7% chance of exploitation in the next 30 days.

Weak JWT Secret vulnerabilitiy in EasyVirt DCScope <= 8.6.0 and CO2Scope <= 1.3.0 allows remote attackers to generate JWT for privilege escalation. The HMAC secret used for generating tokens is hardcoded as "somerandomaccesstoken". A weak HMAC secret poses a risk because attackers can use the predictable secret to create valid JSON Web Tokens (JWTs), allowing them access to important information and actions within the application.

Affected products

• Easyvirt CO2SCOPE: up to and including 1.3.0
• Easyvirt Dcscope: up to and including 8.6.0
