The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5030 advisory.

  • A logic issue was addressed with improved restrictions. This issue is fixed in macOS Monterey 12.0.1, iOS 15.1 and iPadOS 15.1, watchOS 8.1, tvOS 15.1. Processing maliciously crafted web content may lead to unexpectedly unenforced Content Security Policy. (CVE-2021-30887)

  • A logic issue was addressed with improved state management. This issue is fixed in macOS Monterey 12.0.1, iOS 15.1 and iPadOS 15.1, watchOS 8.1, tvOS 15.1. Processing maliciously crafted web content may lead to universal cross site scripting. (CVE-2021-30890)

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