02 Description

Bludit - Remote Code Execution (RCE) through Image API

03 Exploitation and scoring

Exploitation
Public exploit code exists. CISA's assessment records a public proof of concept. That is not a report of exploitation in the wild.
SSVC decision
  • ExploitationpocPublic proof-of-concept exploit code exists. Not a report of exploitation in the wild.
  • AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
  • 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
0.75% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 54.6% of scored records. A rank, not a probability.
NVD base score
8.9 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation

1. Remove tmp-folder from webroot: Ensure that the temporary file directory is relocated outside of the web root to prevent unauthorized access. 2. Remove files from tmp folder even on negative checks: Implement a cleanup process to remove files from the temporary folder, regardless of whether the file extension check is positive or negative. 3. Consolidate image upload code for AJAX requests: It should be noted that there is code for handling image uploads over AJAX (and not through the API) under `bl-kernel/ajax/profile-picture-upload.php`. This code is similar, but different to the API image upload code. For instance, the AJAX code for image uploads includes MIME type validation to provide an additional layer of security. It is advised to consolidate the code into a single location for easier maintenance and ensuring that it is consistent across different parts of the application.
