Description
This security bulletin contains information about 5 vulnerabilities.
1) External Control of File Name or Path (CVE-ID: CVE-2020-12042)
CWE-ID: CWE-73 - External Control of File Name or Path
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/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 the paths specified within the zip files used to update the SoftPAC firmware are not sanitized. A remote authenticated attacker can gain arbitrary file write access with system access.
2) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2020-12046)
CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:N/VI:H/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 SoftPAC’s firmware files’ signatures are not verified upon firmware update. A remote authenticated attacker can replace legitimate firmware files with malicious files.
3) Improper access control (CVE-ID: CVE-2020-10612)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to the SoftPACAgent communicates with SoftPACMonitor over network Port 22000 without any restrictions. A remote attacker can control the SoftPACAgent service including updating SoftPAC firmware, starting or stopping service, or writing to certain registry values.
4) Insecure DLL loading (CVE-ID: CVE-2020-10616)
CWE-ID: CWE-427 - Uncontrolled Search Path Element
CVSSv4: CVSS:4.0/AV:L/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 compromise vulnerable system.
The vulnerability exists due to the application loads DLL libraries in an insecure manner. A remote attacker can place a specially crafted .dll file, trick the victim into opening a file, associated with the vulnerable application, and execute arbitrary code on victim's system.
5) Improper Authorization (CVE-ID: CVE-2020-10620)
CWE-ID: CWE-285 - Improper Authorization
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote user to bypass authorization checks.
The vulnerability exists due to the SoftPAC communication does not include any credentials. A remote attacker can directly communicate with SoftPAC.
