The application attempts to load OpenSSL configuration or library files from a specific filesystem path that is absent by default in standard installations. Because this target directory resides in a location writable by any authenticated local user, a malicious actor can pre-create the directory and place crafted OpenSSL configuration or library files within it. When the Konga application or associated service is executed, it prioritizes loading these attacker-controlled files from the planted path. This results in the execution of arbitrary code with the privileges of the user or service account running the application, potentially leading to full system compromise if the service operates with elevated permissions.

Impact

Successful exploitation allows a local attacker with low-privileged access to escalate their permissions to the level of the Konga application process. In environments where Konga services run as elevated service accounts, this can lead to full administrative control over the host system. This vulnerability affects all Konga deployments on Windows platforms prior to version 2.1.0.

Recommendation

  • Upgrade Konga to version 2.1.0 or later immediately to resolve the insecure library loading behavior.
  • Implement monitoring for the creation of directories within application-specific paths or known high-risk writeable locations by non-administrative users.
  • Audit Windows service configurations to ensure that services running with elevated privileges are not susceptible to DLL hijacking or library loading vulnerabilities.
