CISA Puts Chrome and Magento Zero-Days on Must

CVE-2022-0609 is a use-after-free vulnerability (CWE-416) in the Animation component of Google's Chromium browser engine that can corrupt heap memory. A remote attacker triggers it by persuading a user to load a crafted HTML page (for example via a malicious or compromised website), with no authentication required beyond opening the page. Successful exploitation can lead to heap corruption and potentially arbitrary code execution in the context of the affected browser. Any browser or application built on Chromium is potentially affected, including Google Chrome, Microsoft Edge, and Opera. The flaw is actively exploited: CISA added it to the KEV catalog on 2022-02-15 with a required action to apply vendor updates, Google confirmed in-the-wild exploitation at disclosure, no public PoC is known, ransomware use is unknown, and EPSS assigns a 22.3% probability of exploitation within 30 days (98th percentile).

Do: Apply the vendor updates immediately: Google fixed this in Chrome 98.0.4758.102 (February 2022), so update Chrome, Microsoft Edge, Opera, and any other Chromium-based browsers or Chromium-embedded applications to releases containing that Chromium fix, and inventory browser versions across your fleet to catch machines lagging on the update. Until fully patched, treat unsolicited links to web pages as an exploitation vector given confirmed in-the-wild use, and comply with CISA's KEV required action to apply updates per vendor instructions.

Adobe Commerce and Magento Open Source versions 2.4.3-p1 and earlier and 2.3.7-p2 and earlier contain an improper input validation flaw (CWE-20) in the checkout process. A remote attacker can trigger it with no privileges and no user interaction by submitting crafted input to a store's checkout flow, and successful exploitation results in arbitrary code execution on the server hosting the storefront. Any Adobe Commerce or Magento Open Source storefront running the affected versions is exposed, and because these are internet-facing e-commerce sites the practical exposure is broad. Exploitation is confirmed in the wild: the flaw is in CISA's Known Exploited Vulnerabilities catalog (added 2022-02-15), its EPSS exploitation probability is 99.2% (100th percentile), and news reports describe ongoing attacks against Magento 2 stores, including recurring 'Xurum' attack campaigns and template-based attacks.

Do: Upgrade every store to an Adobe-patched release per the vendor's instructions - i.e., any release newer than 2.4.3-p1 on the 2.4.x line or newer than 2.3.7-p2 on the 2.3.x line - noting that headlines indicate companion Magento CVEs were fixed in the same patch release, so consult Adobe's advisory for the full list. Because exploitation is unauthenticated and confirmed in the wild, prioritize internet-facing shops; WAF rules may reduce risk, but reports indicate WAF bypasses in related Magento attacks, so patching is the only reliable fix. After patching, review web server and application logs for exploitation attempts against the checkout flow and check affected hosts for indicators of compromise.
