Description
This security bulletin contains information about 4 vulnerabilities.
1) NULL pointer dereference (CVE-ID: N/A)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to a NULL pointer dereference error when the application allows a cookie parameter to consist of only digits. A remote attacker can perform a brute force attack and gain access to device functions.
2) Integer overflow (CVE-ID: N/A)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/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 integer overflow. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.
3) Out-of-bounds read (CVE-ID: N/A)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to a boundary condition. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) atack.
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
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 DoS attack on the target system.
The vulnerability exists due memory leak. A remote attacker can force the application to leak memory and perform denial of service attack.
