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

The remote NewStart CGSL host, running version MAIN 6.06, has mokutil packages installed that are affected by multiple vulnerabilities:

  - A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may     take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent     secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform     some triage over the heap layout to achieve signifcant results, also the values written into the memory     are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2     versions prior grub-2.12. (CVE-2021-3695)

  - A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may     lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be     considered Low as it's very complex to an attacker control the encoding and positioning of corrupted     Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This     flaw affects grub2 versions prior grub-2.12. (CVE-2021-3696)

  - A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data     to be written in heap. To a successful to be performed the attacker needs to perform some triage over the     heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data     corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions     prior grub-2.12. (CVE-2021-3697)

  - Integer underflow in grub_net_recv_ip4_packets; A malicious crafted IP packet can lead to an integer     underflow in grub_net_recv_ip4_packets() function on rsm->total_len value. Under certain circumstances the     total_len value may end up wrapping around to a small integer number which will be used in memory     allocation. If the attack succeeds in such way, subsequent operations can write past the end of the     buffer. (CVE-2022-28733)

  - Out-of-bounds write when handling split HTTP headers; When handling split HTTP headers, GRUB2 HTTP code     accidentally moves its internal data buffer point by one position. This can lead to a out-of-bound write     further when parsing the HTTP request, writing a NULL byte past the buffer. It's conceivable that an     attacker controlled set of packets can lead to corruption of the GRUB2's internal memory metadata.
    (CVE-2022-28734)

  - The GRUB2's shim_lock verifier allows non-kernel files to be loaded on shim-powered secure boot systems.
    Allowing such files to be loaded may lead to unverified code and modules to be loaded in GRUB2 breaking     the secure boot trust-chain. (CVE-2022-28735)

  - There's a use-after-free vulnerability in grub_cmd_chainloader() function; The chainloader command is used     to boot up operating systems that doesn't support multiboot and do not have direct support from GRUB2.
    When executing chainloader more than once a use-after-free vulnerability is triggered. If an attacker can     control the GRUB2's memory allocation pattern sensitive data may be exposed and arbitrary code execution     can be achieved. (CVE-2022-28736)

  - There's a possible overflow in handle_image() when shim tries to load and execute crafted EFI executables;
    The handle_image() function takes into account the SizeOfRawData field from each section to be loaded. An     attacker can leverage this to perform out-of-bound writes into memory. Arbitrary code execution is not     discarded in such scenario. (CVE-2022-28737)

    It was discovered that GRUB2 configuration files were created with the wrong permissions. An attacker     could possibly use this to leak encrypted passwords. (CVE-2021-3981)

    Daniel Axtens discovered that specially crafted IP packets could cause an integer underflow and write past     the end of a buffer. An attacker could possibly use this to circumvent secure boot protections.
    (CVE-2022-28733)

    Daniel Axtens discovered that specially crafted HTTP headers can cause an out-of-bounds write of a NULL     byte. An attacker could possibly use this to corrupt GRUB2's internal data. (CVE-2022-28734)

    Julian Andres Klode discovered that GRUB2 shim_lock allowed non- kernel files to be loaded. A local attack     could possibly use this to circumvent secure boot protections. (CVE-2022-28735)

The remote NewStart CGSL host, running version MAIN 6.02, has grub2 packages installed that are affected by multiple vulnerabilities:

  - A flaw in grub2 was found where its configuration file, known as grub.cfg, is being created with the wrong     permission set allowing non privileged users to read its content. This represents a low severity     confidentiality issue, as those users can eventually read any encrypted passwords present in grub.cfg.
    (CVE-2021-3981)

  - A flaw was found in grub2 when handling IPv4 packets. This flaw allows an attacker to craft a malicious     packet, triggering an integer underflow in grub code. Consequently, the memory allocation for handling the     packet data may be smaller than the size needed. This issue causes an out-of-bands write during packet     handling, compromising data integrity, confidentiality issues, a denial of service, and remote code     execution. (CVE-2022-28733)

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

The remote Scientific Linux 7 host has packages installed that are affected by a vulnerability as referenced in the SLSA-2022:8900-1 advisory.

  - grub2: Integer underflow in grub_net_recv_ip4_packets (CVE-2022-28733)

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

According to the versions of the grub2 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may     take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent     secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform     some triage over the heap layout to achieve signifcant results, also the values written into the memory     are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2     versions prior grub-2.12. (CVE-2021-3695)

  - A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may     lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be     considered Low as it's very complex to an attacker control the encoding and positioning of corrupted     Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This     flaw affects grub2 versions prior grub-2.12. (CVE-2021-3696)

  - A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data     to be written in heap. To a successful to be performed the attacker needs to perform some triage over the     heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data     corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions     prior grub-2.12. (CVE-2021-3697)

  - grub2: Integer underflow in grub_net_recv_ip4_packets (CVE-2022-28733)

  - grub2: Out-of-bound write when handling split HTTP headers (CVE-2022-28734)

  - grub2: shim_lock verifier allows non-kernel files to be loaded (CVE-2022-28735)

  - grub2: use-after-free in grub_cmd_chainloader() (CVE-2022-28736)

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 SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2074-1 advisory.

The version of AOS installed on the remote host is prior to 6.5.3. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.5.3 advisory.

  - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create     user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to     a use-after-free. (CVE-2022-32250)

  - zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a     large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some     common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g.,     see the nodejs/node reference). (CVE-2022-37434)

  - mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse.
    (CVE-2022-42703)

  - A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain     kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2022-4378)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE     (component: Serialization). Supported versions that are affected are Oracle Java SE: 8u351, 8u351-perf;
    Oracle GraalVM Enterprise Edition: 20.3.8 and 21.3.4. Easily exploitable vulnerability allows     unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle     GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update,     insert or delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data.
    Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web     Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from     the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java     deployments, typically in servers, that load and run only trusted code (e.g., code installed by an     administrator). (CVE-2023-21830)
