Missing Server-Side Authentication Checks in EfficientLab WorkExaminer Professional

03 Exploitation and scoring

Exploitation
Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
  • Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.90% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 59.3% of scored records. A rank, not a probability.
NVD base score
9.8 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector

07 Remediation

The vendor responded to the submission of our security vulnerabilities by stating that they are not within the scope of their bug bounty program. After telling them that we do not care about the bug bounty but a fix for the issues, we did not receive any further response. Hence, there is no fix available for the identified security issues and we assume that this product is unmaintained. We urge customers to contact EfficientLab regarding the issues and a potential solution, such as using another product.
