In Fluent Bit 2.1.8 through 2.2.1, a NULL pointer dereference can be caused via an invalid HTTP payload with the content type of x-www-form-urlencoded. It crashes and does not restart. This could result in logs not being delivered properly.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In Fluent Bit 2.1.8 through 2.2.1, a NULL pointer dereference can be caused via an invalid HTTP payload     with the content type of x-www-form-urlencoded. It crashes and does not restart. This could result in logs     not being delivered properly. (CVE-2024-23722)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7250-1 advisory.

    It was discovered that Netdata incorrectly handled parsing JSON input, which could lead to a JSON     injection. An attacker could possibly use this issue to execute arbitrary code. This issue only affected

    Ubuntu 18.04 LTS. (CVE-2018-18836)

    It was discovered that Netdata incorrectly handled parsing HTTP headers, which could lead to a HTTP header     injection. An attacker could possibly use this issue to cause a denial of service or leak sensitive     information. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-18837)

    It was discovered that Netdata incorrectly handled parsing URLs, which could lead to a log injection. An     attacker could possibly use this issue to consume system resources, resulting in a denial of service. This     issue only affected Ubuntu 18.04 LTS. (CVE-2018-18838)

    It was discovered Netdata improperly authenticated API keys. An attacker could possibly use this issue to     leak sensitive information or execute arbitrary code. This issue only affected Ubuntu 20.04 LTS and

    Ubuntu 22.04 LTS. (CVE-2023-22497)

    It was discovered Fluent Bit, vendored in Netdata, incorrectly handled parsing HTTP payloads. An attacker     could possibly use this issue to disrupt logging. This issue only affected Ubuntu 24.10. (CVE-2024-23722)

    It was discovered that WebAssembly Micro Runtime, vendored in Netdata, incorrectly handled memory. An     attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu     24.10. (CVE-2024-34250, CVE-2024-34251)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The version of fluent-bit installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-23722 advisory.
