Online Grades 3.2.4 allows remote attackers to obtain configuration information via a direct request to phpinfo.php, which calls the phpinfo

Noroxi assessment

Priority: Monitor (action score 21/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.6% (FIRST EPSS); higher than 85% of all records.
  • No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.
