The version of AOS installed on the remote host is prior to 6.0.2.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.0.2.5 advisory.

  - xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and     watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows     remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory     corruption) via a crafted XML document. (CVE-2016-4658)

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for     certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how     they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and     PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and     Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
    (CVE-2021-43527)

  - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass     RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users     with the ability to start and control a VM to read/write random pages of memory and can result in local     privilege escalation. (CVE-2021-22543)

  - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when     processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested     guest (L2). Due to improper validation of the int_ctl field, this issue could allow a malicious L1 to     enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest     would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak     of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to     5.14-rc7. (CVE-2021-3653)

  - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when     processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested     guest (L2). Due to improper validation of the virt_ext field, this issue could allow a malicious L1 to     disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the     L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire     system, leak of sensitive data or potential guest-to-host escape. (CVE-2021-3656)

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

An update of the httpd package has been released.

According to the versions of the httpd packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP     Server 2.4.48 and earlier. (CVE-2021-34798)

  - ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules     pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache     HTTP Server 2.4.48 and earlier. (CVE-2021-39275)

  - A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the     remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. (CVE-2021-40438)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has httpd packages installed that are affected by multiple vulnerabilities:

  - In Apache HTTP Server versions 2.4.0 to 2.4.46 a specially crafted SessionHeader sent by an origin server     could cause a heap overflow (CVE-2021-26691)

  - Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP     Server 2.4.48 and earlier. (CVE-2021-34798)

  - ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules     pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache     HTTP Server 2.4.48 and earlier. (CVE-2021-39275)

  - A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the     remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. (CVE-2021-40438)

  - A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser     (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the     vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and     earlier. (CVE-2021-44790)

  - Apache HTTP Server 2.4.52 and earlier fails to close inbound connection when errors are encountered     discarding the request body, exposing the server to HTTP Request Smuggling (CVE-2022-22720)

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