Google Chrome: Improper input validation in Passwords component
Summary
Improper input validation in the Passwords component of Google Chrome before 156.0.8078.47 allows a remote attacker to potentially execute arbitrary code outside the browser sandbox. The attacker needs the victim to visit a crafted HTML page, and no authentication is required. Google rates the flaw Medium, while the NVD CVSS score is 9.6 Critical, and no public exploitation or proof of concept was known at the time of research.
Affected
- Google Chrome prior to 156.0.8078.47 (per CVE description)
- Linux and Android: builds before 156.0.8078.47
- Windows and macOS: builds before 156.0.8078.47 or 156.0.8078.48 (secondary sources)
- Chromium-based browsers may inherit the flaw until they ship the Chromium fix
Fixed in
- Chrome 156.0.8078.47 for Linux and Android (Android not confirmed)
- Chrome 156.0.8078.47 or 156.0.8078.48 for Windows and macOS (secondary sources)
- Unknown for other Chromium-based browsers in this entry, except that Microsoft Edge 156.0.4314.42 or later is reported as fixed
Workaround
No workaround documented. Update Chrome and restart the browser afterwards.
Exploitation
- No known exploitation in the wild at time of research
- Not listed in CISA KEV according to a third-party tracker (not verified directly)
- No public proof of concept found
- EPSS about 0.5 percent according to Vulners
Our recommendation
- Update Chrome on all desktop systems to the fixed version and restart the browser
- Verify the installed version on each machine, not only whether an update was offered
- Check that Chromium-based browsers used in the company are updated as well
- Treat the update as high priority, because the attack requires only a web visit and the browser stores credentials
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
