Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Resource exhaustion
EUVDB-ID: #VU81728
Risk: High
CVSSv3.1: 5.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:H/RL:O/RC:C]
CVE-ID: CVE-2023-44487
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".
Note, the vulnerability is being actively exploited in the wild.
Install update from vendor's website.
Vulnerable software versionsVoice Gateway: 1.0.2 - 1.0.8

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?
Yes. This vulnerability is being exploited in the wild.
2) Code Injection
EUVDB-ID: #VU82070
Risk: Low
CVSSv3.1: 2.7 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-39333
CWE-ID:
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary JavaScript code.
The vulnerability exists due to improper input validation in an imported WebAssembly module when processing export names. A remote attacker can pass specially crafted export names to the application and execute arbitrary JavaScript code on the system.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote authenticated user via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
3) Improper validation of integrity check value
EUVDB-ID: #VU82069
Risk: Medium
CVSSv3.1: 5.5 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-38552
CWE-ID:
CWE-354 - Improper Validation of Integrity Check Value
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an error in the policy feature, which checks the integrity of a resource against a trusted manifest. An application can intercept the operation and return a forged checksum to node's policy implementation, thus effectively disabling the integrity check.
