CVE-2022-31631: PDO::quote() may return unquoted string

CriticalCVSS 9.1 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 37/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.1% (FIRST EPSS); higher than 82.6% 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.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: PHP Group PHP 8.0.27, 8.1.15, 8.2.2.

Low priority for now. Upgrade to PHP Group PHP 8.0.27, 8.1.15, 8.2.2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In PHP versions 8.0.* before 8.0.27, 8.1.* before 8.1.15, 8.2.* before 8.2.2 when using PDO::quote() function to quote user-supplied data for SQLite, supplying an overly long string may cause the driver to incorrectly quote the data, which may further lead to SQL injection vulnerabilities.
