Description
This security bulletin contains information about 9 vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: N/A)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. A remote administrator on the local network can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Command Injection (CVE-ID: N/A)
CWE-ID: CWE-77 - Command injection
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to execute arbitrary commands on the target system.
The vulnerability exists due to improper input validation. A local user can pass specially crafted data to the application and execute arbitrary commands on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Command Injection (CVE-ID: N/A)
CWE-ID: CWE-77 - Command injection
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to execute arbitrary commands on the target system.
The vulnerability exists due to improper input validation. A remote administrator on the local network can pass specially crafted data to the application and execute arbitrary commands on the target system.

4) Configuration (CVE-ID: N/A)
CWE-ID: CWE-16 - Configuration
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to compromise the target system.
The vulnerability exists due to misconfiguration issue. A local user can bypass authentication process and gain unauthorized access to the application.
5) Command Injection (CVE-ID: N/A)
CWE-ID: CWE-77 - Command injection
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to execute arbitrary commands on the target system.
The vulnerability exists due to improper input validation. A local user can pass specially crafted data to the application and execute arbitrary commands on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Input validation error (CVE-ID: N/A)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
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 on the local network can pass specially crafted input to the application and perform a denial of service (DoS) attack.
7) Stack-based buffer overflow (CVE-ID: N/A)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error. A remote administrator on the local network can trigger stack-based buffer overflow and cause a denial of service condition on the target system.
8) Stack-based buffer overflow (CVE-ID: N/A)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
