The version of Microsoft Edge installed on the remote Windows host is prior to 127.0.2651.86. It is, therefore, affected by multiple vulnerabilities as referenced in the August 1, 2024 advisory.
Uninitialized Use in Dawn in Google Chrome on Android prior to 127.0.6533.88 allowed a remote attacker to potentially perform out of bounds memory access via a crafted HTML page. (Chromium security severity:
Critical) (CVE-2024-6990)
Out of bounds read in WebTransport in Google Chrome prior to 127.0.6533.88 allowed a remote attacker to potentially perform out of bounds memory access via a crafted HTML page. (Chromium security severity:
High) (CVE-2024-7255)
Insufficient data validation in Dawn in Google Chrome on Android prior to 127.0.6533.88 allowed a remote attacker to execute arbitrary code via a crafted HTML page. (Chromium security severity: High) (CVE-2024-7256)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
