Description
This security bulletin contains information about 7 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:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing untrusted input at the IEEE802.1x setting page in web interface. A remote unauthenticated attacker can send specially crafted request to the affected device, 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) Use of a broken or risky cryptographic algorithm (CVE-ID: N/A)
CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to usage of weak cryptographic algorithm. A remote non-authenticated attacker with ability to perform man-in-the-middle attack can intercept and decrypt sensitive data (e.g. device configuration), passed via insecure channel.
3) Use of Hard-coded Cryptographic Key (CVE-ID: N/A)
CWE-ID: CWE-321 - Use of Hard-coded Cryptographic Key
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to firmware uses a hard-coded cryptographic key. A local user can obtain the key and decrypt files with sensitive information.
4) Use of hard-coded credentials (CVE-ID: N/A)
CWE-ID: CWE-798 - Use of Hard-coded Credentials
CVSSv4: CVSS:4.0/AV:A/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 gain full access to vulnerable system.
The vulnerability exists due to presence of hard-coded credentials in application code. A remote unauthenticated attacker can access the affected system using the hard-coded credentials.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Buffer overflow (CVE-ID: N/A)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:A/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 denial of service attack.
The vulnerability exists due to a boundary error when processing data passed via the DHCP setting and PTP setting in web interface. A remote attacker can send a specially crafted request to the affected device, trigger memory corruption and perform denial of service (DoS) attack.
6) Cleartext transmission of sensitive information (CVE-ID: N/A)
CWE-ID: CWE-319 - Cleartext Transmission of Sensitive Information
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to software uses by default insecure communication channel to transmit sensitive information. A remote attacker with ability to intercept network traffic can gain access to sensitive data.
7) Weak password requirements (CVE-ID: N/A)
CWE-ID: CWE-521 - Weak Password Requirements
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows an attacker to perform brute-force attack and guess the password.
The vulnerability exists due to weak password requirements. An attacker can perform a brute-force attack and guess users' passwords.
