The version of Microsoft Edge installed on the remote Windows host is prior to 95.0.1020.40. It is, therefore, affected by multiple vulnerabilities as referenced in the October 29, 2021 advisory.

  • Inappropriate implementation in V8 in Google Chrome prior to 95.0.4638.69 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2021-38003)

  • Use after free in Sign-In in Google Chrome prior to 95.0.4638.69 allowed a remote attacker who convinced a user to sign into Chrome to potentially exploit heap corruption via a crafted HTML page. (CVE-2021-37997)

  • Use after free in Garbage Collection in Google Chrome prior to 95.0.4638.69 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2021-37998)

  • Insufficient data validation in New Tab Page in Google Chrome prior to 95.0.4638.69 allowed a remote attacker to inject arbitrary scripts or HTML in a new browser tab via a crafted HTML page.
    (CVE-2021-37999)

  • Insufficient validation of untrusted input in Intents in Google Chrome on Android prior to 95.0.4638.69 allowed a remote attacker to arbitrarily browser to a malicious URL via a crafted HTML page.
    (CVE-2021-38000)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
