The version of busybox 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-2021-42376 advisory.

  - A NULL pointer dereference in Busybox's hush applet leads to denial of service when processing a crafted     shell command, due to missing validation after a \x03 delimiter character. This may be used for DoS under     very rare conditions of filtered command input. (CVE-2021-42376)

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 busybox package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The recv_and_process_client_pkt function in networking/ntpd.c in busybox allows remote attackers to cause     a denial of service (CPU and bandwidth consumption) via a forged NTP packet, which triggers a     communication loop. (CVE-2016-6301)

  - The get_next_block function in archival/libarchive/decompress_bunzip2.c in BusyBox 1.27.2 has an Integer     Overflow that may lead to a write access violation. (CVE-2017-15873)

  - archival/libarchive/decompress_unlzma.c in BusyBox 1.27.2 has an Integer Underflow that leads to a read     access violation. (CVE-2017-15874)

  - In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2, the tab autocomplete feature of     the shell, used to get a list of filenames in a directory, does not sanitize filenames and results in     executing any escape sequence in the terminal. This could potentially result in code execution, arbitrary     file writes, or other attacks. (CVE-2017-16544)

  - Busybox contains a Missing SSL certificate validation vulnerability in The busybox wget applet that can     result in arbitrary code execution. This attack appear to be exploitable via Simply download any file over     HTTPS using busybox wget https://compromised-domain.com/important-file. (CVE-2018-1000500)

  - BusyBox project BusyBox wget version prior to commit 8e2174e9bd836e53c8b9c6e00d1bc6e2a718686e contains a     Buffer Overflow vulnerability in Busybox wget that can result in heap buffer overflow. This attack appear     to be exploitable via network connectivity. This vulnerability appears to have been fixed in after commit     8e2174e9bd836e53c8b9c6e00d1bc6e2a718686e. (CVE-2018-1000517)

  - An issue was discovered in BusyBox before 1.30.0. An out of bounds read in udhcp components (consumed by     the DHCP server, client, and relay) allows a remote attacker to leak sensitive information from the stack     by sending a crafted DHCP message. This is related to verification in udhcp_get_option() in     networking/udhcp/common.c that 4-byte options are indeed 4 bytes. (CVE-2018-20679)

  - An issue was discovered in BusyBox through 1.30.0. An out of bounds read in udhcp components (consumed by     the DHCP client, server, and/or relay) might allow a remote attacker to leak sensitive information from     the stack by sending a crafted DHCP message. This is related to assurance of a 4-byte length when decoding     DHCP_SUBNET. NOTE: this issue exists because of an incomplete fix for CVE-2018-20679. (CVE-2019-5747)

  - decompress_gunzip.c in BusyBox through 1.32.1 mishandles the error bit on the huft_build result pointer,     with a resultant invalid free or segmentation fault, via malformed gzip data. (CVE-2021-28831)

  - A NULL pointer dereference in Busybox's man applet leads to denial of service when a section name is     supplied but no page argument is given (CVE-2021-42373)

  - An out-of-bounds heap read in Busybox's unlzma applet leads to information leak and denial of service when     crafted LZMA-compressed input is decompressed. This can be triggered by any applet/format that     (CVE-2021-42374)

  - An incorrect handling of a special element in Busybox's ash applet leads to denial of service when     processing a crafted shell command, due to the shell mistaking specific characters for reserved     characters. This may be used for DoS under rare conditions of filtered command input. (CVE-2021-42375)

  - A NULL pointer dereference in Busybox's hush applet leads to denial of service when processing a crafted     shell command, due to missing validation after a \x03 delimiter character. This may be used for DoS under     very rare conditions of filtered command input. (CVE-2021-42376)

  - An attacker-controlled pointer free in Busybox's hush applet leads to denial of service and possible code     execution when processing a crafted shell command, due to the shell mishandling the &&& string. This may     be used for remote code execution under rare conditions of filtered command input. (CVE-2021-42377)

  - A use-after-free in Busybox's awk applet leads to denial of service and possibly code execution when     processing a crafted awk pattern in the getvar_i function (CVE-2021-42378)

  - A use-after-free in Busybox's awk applet leads to denial of service and possibly code execution when     processing a crafted awk pattern in the next_input_file function (CVE-2021-42379)

  - A use-after-free in Busybox's awk applet leads to denial of service and possibly code execution when     processing a crafted awk pattern in the clrvar function (CVE-2021-42380)

  - A use-after-free in Busybox's awk applet leads to denial of service and possibly code execution when     processing a crafted awk pattern in the getvar_s function (CVE-2021-42382)

  - A use-after-free in Busybox's awk applet leads to denial of service and possibly code execution when     processing a crafted awk pattern in the evaluate function (CVE-2021-42383, CVE-2021-42385)

  - A use-after-free in Busybox's awk applet leads to denial of service and possibly code execution when     processing a crafted awk pattern in the handle_special function (CVE-2021-42384)

  - A use-after-free in Busybox's awk applet leads to denial of service and possibly code execution when     processing a crafted awk pattern in the nvalloc function (CVE-2021-42386)
