Calling `PK11_Encrypt()` in NSS using CKM_CHACHA20 and the same buffer for input and output can result in plaintext on an Intel Sandy Bridge processor. In Firefox this only affects the QUIC header protection feature when the connection is using the ChaCha20-Poly1305 cipher suite. The most likely outcome is connection failure, but if the connection persists despite the high packet loss it could be possible for a network observer to identify packets as coming from the same source despite a network path change. This vulnerability affects Firefox < 129, Firefox ESR < 115.14, and Firefox ESR < 128.1.

The version of firefox installed on the remote host is prior to 115.14.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2FIREFOX-2024-030 advisory.

    Insufficient checks when processing graphics shared memory could have led to memory corruption. This could     be leveraged by an attacker to perform a sandbox escape. This vulnerability affects Firefox < 129, Firefox     ESR < 115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and Thunderbird < 115.14. (CVE-2024-7519)

    Incomplete WebAssembly exception handing could have led to a use-after-free. This vulnerability affects     Firefox < 129, Firefox ESR < 115.14, and Firefox ESR < 128.1. (CVE-2024-7521)

    Editor code failed to check an attribute value. This could have led to an out-of-bounds read. This     vulnerability affects Firefox < 129, Firefox ESR < 115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and     Thunderbird < 115.14. (CVE-2024-7522)

    Firefox adds web-compatibility shims in place of some tracking scripts blocked by Enhanced Tracking     Protection.  On a site protected by Content Security Policy in strict-dynamic mode, an attacker able to     inject an HTML element could have used a DOM Clobbering attack on some of the shims and achieved XSS,     bypassing the CSP strict-dynamic protection. This vulnerability affects Firefox < 129, Firefox ESR <     115.14, and Firefox ESR < 128.1. (CVE-2024-7524)

    It was possible for a web extension with minimal permissions to create a `StreamFilter` which could be     used to read and modify the response body of requests on any site. This vulnerability affects Firefox <     129, Firefox ESR < 115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and Thunderbird < 115.14.
    (CVE-2024-7525)

    ANGLE failed to initialize parameters which led to reading from uninitialized memory. This could be     leveraged to leak sensitive data from memory. This vulnerability affects Firefox < 129, Firefox ESR <     115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and Thunderbird < 115.14. (CVE-2024-7526)

    Unexpected marking work at the start of sweeping could have led to a use-after-free. This vulnerability     affects Firefox < 129, Firefox ESR < 115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and Thunderbird <     115.14. (CVE-2024-7527)

    The date picker could partially obscure security prompts. This could be used by a malicious site to trick     a user into granting permissions. This vulnerability affects Firefox < 129, Firefox ESR < 115.14, Firefox     ESR < 128.1, Thunderbird < 128.1, and Thunderbird < 115.14. (CVE-2024-7529)

    Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information across domains, or execute arbitrary code.

  - Editor code failed to check an attribute value. This could have led to an out-of-bounds read.
    (CVE-2024-7522)

  - A select option could partially obscure security prompts. This could be used by a malicious site to trick     a user into granting permissions.  This issue only affects Android versions of Firefox. (CVE-2024-7523)

  - Firefox adds web-compatibility shims in place of some tracking scripts blocked by Enhanced Tracking     Protection.  On a site protected by Content Security Policy in strict-dynamic mode, an attacker able to     inject an HTML element could have used a DOM Clobbering attack on some of the shims and achieved XSS,     bypassing the CSP strict-dynamic protection. (CVE-2024-7524)

  - It was possible for a web extension with minimal permissions to create a <code>StreamFilter</code> which     could be used to read and modify the response body of requests on any site. (CVE-2024-7525)

  - ANGLE failed to initialize parameters which lead to reading from uninitialized memory. This could be     leveraged to leak sensitive data from memory. (CVE-2024-7526)

  - Unexpected marking work at the start of sweeping could have led to a use-after-free. (CVE-2024-7527)

  - Incorrect garbage collection interaction in IndexedDB could have led to a use-after-free. (CVE-2024-7528)

  - The date picker could partially obscure security prompts. This could be used by a malicious site to trick     a user into granting permissions. (CVE-2024-7529)

  - Incorrect garbage collection interaction could have led to a use-after-free. (CVE-2024-7530)

  - Calling <code>PK11Encrypt()</code> in NSS using CKMCHACHA20 and the same buffer for input and output can     result in plaintext on an Intel Sandy Bridge processor. In Firefox this only affects the QUIC header     protection feature when the connection is using the ChaCha20-Poly1305 cipher suite. The most likely     outcome is connection failure, but if the connection persists despite the high packet loss it could be     possible for a network observer to identify packets as coming from the same source despite a network path     change. (CVE-2024-7531)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
