CriticalCVSS 9.8 · v3.0—Weaponized Fix available

Noroxi assessment

Priority: This week (action score 61/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • 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: 72.1% (FIRST EPSS); higher than 99.4% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: codeigniter/framework (Packagist) 3.0.0; kohana/core (Packagist) 3.3.3.

Don’t wait for the next maintenance window. Upgrade to codeigniter/framework (Packagist) 3.0.0; kohana/core (Packagist) 3.3.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

CodeIgniter before 3.0 and Kohana 3.2.3 and earlier and 3.3.x through 3.3.2 make it easier for remote attackers to spoof session cookies and consequently conduct PHP object injection attacks by leveraging use of standard string comparison operators to compare cryptographic hashes.
