Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Improper validation of certificate with host mismatch
EUVDB-ID: #VU59549
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-44532
CWE-ID:
CWE-297 - Improper Validation of Certificate with Host Mismatch
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to improper validation of certificates, when converting SANs (Subject Alternative Names) to a string format. A remote attacker can inject special characters into the string and perform spoofing attack.
Install update from vendor's website.
Vulnerable software versionsVoice Gateway: 1.0.7.0 - 1.0.7.11

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Improper Certificate Validation
EUVDB-ID: #VU59550
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-44533
CWE-ID:
CWE-295 - Improper Certificate Validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to improper validation of certificate subject and issuer fields. A remote attacker can create a certificate with specially crafted multi-value Relative Distinguished Names and perform spoofing attack.
Install update from vendor's website.

3) Infinite loop
EUVDB-ID: #VU61391
Risk: Medium
CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2022-0778
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the BN_mod_sqrt() function when processing an ASN.1 certificate that contains elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form. A remote attacker can supply a specially crafted certificate to the TLS server or client, consume all available system resources and cause denial of service conditions.
MitigationInstall update from vendor's website.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
4) Improper Certificate Validation
EUVDB-ID: #VU59548
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-44531
CWE-ID:
CWE-295 - Improper Certificate Validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform spoofing attack.
The
vulnerability exists due to insufficient validation of URI Subject
Alternative Names. Node.js accepts arbitrary Subject Alternative Name
(SAN) types, unless a PKI
is specifically defined to use a particular SAN type. A remote attacker
can bypass name-constrained intermediates and perform spoofing attack.
