Why Organizations Need to Patch a Critical Zero-Day in Chrome
Emergency update released to address CVE-2022-1096 as reports swirl of exploitation
Another week, another critical zero-day vulnerability to patch. This time it’s an emergency update issued by Google for a flaw that could allow attackers to run arbitrary code on victim machines. It’s been found in both Chrome and Microsoft’s Chromium-based Edge products. Given the popularity of these browsers, it’s likely that most organizations will need to take action.
Fortunately, Tanium enables customers to find, remediate and track the vulnerability at speed and scale across their entire endpoint estate.
What is CVE-2022-1096?
According to reports, the bug is being exploited in at least one phishing campaign targeting individuals in the crypto space, using Discord as an initial vector.
Why should you care?
Google claimed in its emergency notice that CVE-2022-1096 is already being actively exploited in the wild, hence its rapidity in issuing the update. The patch was said to have been published within two days of being reported. The firm also thought it serious enough to issue a standalone update to the browser (99.0.4844.84) for this single issue, rather than wait to fold several fixes into the release, as is usually the case. That hints at its criticality. Microsoft has also released an updated version of its Edge browser (99.0.1150.55) to mitigate the threat.
Another indication of the vulnerability’s seriousness is that is has been added to the Known Exploited Bug Catalog maintained by the US Cybersecurity & Infrastructure Security Agency (CISA). The agency has demanded all civilian federal government agencies patch the flaw by April 18. Although the catalog applies specifically to government entities, CISA has in the past urged all organizations to prioritize mitigation of the vulnerabilities it lists, which are now several hundred in number.
