Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Use of a broken or risky cryptographic algorithm
EUVDB-ID: #VU62039
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-27191
CWE-ID:
CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error in golang.org/x/crypto/ssh before 0.0.0-20220314234659-1baeb1ce4c0b, as used in Go programming language. A remote attacker can crash a server in certain circumstances involving AddHostKey.
MitigationInstall update from vendor's website.
Vulnerable software versionsnode_exporter: 1.0.0 - 1.4.0
External linkshttp://github.com/prometheus/node_exporter/releases/tag/v1.4.1
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

No. We are not aware of malware exploiting this vulnerability.
2) Input validation error
EUVDB-ID: #VU67396
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-27664
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
MitigationInstall update from vendor's website.
Vulnerable software versionsnode_exporter: 1.0.0 - 1.4.0

3) Use of Password Hash Instead of Password for Authentication
EUVDB-ID: #VU69691
Risk: Low
CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-46146
CWE-ID:
CWE-836 - Use of Password Hash Instead of Password for Authentication
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to incorrect implementation of basic authentication. A remote attacker with knowledge of the password hash can authenticate against Prometheus without actual knowledge of the password.
