CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to key exchange without entity authentication. A remote authenticated attacker can bypass authentication process and gain elevated privileges on the system.


2) Improper Resource Shutdown or Release (CVE-ID: CVE-2021-0132)

CWE-ID: CWE-404 - Improper Resource Shutdown or Release

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:A/VC:N/VI:N/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 missing release of resource after effective lifetime in an API. A remote administrator can cause a denial of service condition on the target system.


3) Cryptographic issues (CVE-ID: CVE-2021-0131)

CWE-ID: CWE-310 - Cryptographic Issues

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:L/VI:L/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 use of cryptographically weak pseudo-random number generator (PRNG) in an API. A remote authenticated attacker can gain unauthorized access to sensitive information on the system.


4) Input validation error (CVE-ID: CVE-2021-0134)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:A/VC:N/VI:N/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 insufficient validation of user-supplied input in an API. A remote administrator can pass specially crafted input to the application and perform a denial of service (DoS) attack.
