Description
This security bulletin contains information about 9 vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2023-20024)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing requests sent to the web interface. A remote non-authenticated attacker can send a specially crafted request to the web interface, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.
2) Heap-based buffer overflow (CVE-ID: CVE-2023-20156)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing requests sent to the web interface. A remote non-authenticated attacker can send a specially crafted request to the web interface, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.
3) Heap-based buffer overflow (CVE-ID: CVE-2023-20157)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing requests sent to the web interface. A remote non-authenticated attacker can send a specially crafted request to the web interface, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.
4) Input validation error (CVE-ID: CVE-2023-20158)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send specially crafted input to the web interface and perform a denial of service (DoS) attack.
5) Stack-based buffer overflow (CVE-ID: CVE-2023-20159)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling requests. A remote unauthenticated attacker can send specially crafted input to the web interface, trigger a stack-based buffer overflow and execute arbitrary code with root privileges on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Buffer overflow (CVE-ID: CVE-2023-20160)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling requests. A remote unauthenticated attacker can send specially crafted input to the web interface, trigger a based buffer overflow and execute arbitrary code with root privileges on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Stack-based buffer overflow (CVE-ID: CVE-2023-20161)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling requests. A remote unauthenticated attacker can send specially crafted input to the web interface, trigger a stack-based buffer overflow and execute arbitrary code with root privileges on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) Information disclosure (CVE-ID: CVE-2023-20162)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output in the web interface. A remote attacker can read system configuration.
9) Stack-based buffer overflow (CVE-ID: CVE-2023-20189)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling requests. A remote unauthenticated attacker can send specially crafted input to the web interface, trigger a stack-based buffer overflow and execute arbitrary code with root privileges on the target system.
