Today, the developer reported that the he is not able to upload some files.
As we checked, we were getting the following error on mod_security log.
Message: Input filter: Failed to create temporary file: /var/lib/mod_security/20231027-063404-ZTtZ3Bs-KzTcnh@YiPa2YAAAAAw-request_body-Yidqhf Message: Audit log: Failed to lock global mutex: Permission deni
It looks like apache is getting denied while writing in to /var/lib/mod_security/ location.
As a quick fix, we have modified the
mod_security.conf configuration file located at
SecRequestBodyAccess On #SecTmpDir /var/lib/mod_security #SecDataDir /var/lib/mod_security SecTmpDir /tmp SecDataDir /tmp
Once modified, restarted the service with
systemctl restart httpd command and the developer was able to upload the files.
