Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Improper Neutralization of HTTP Headers for Scripting Syntax
EUVDB-ID: #VU78327
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-2023-29406
CWE-ID:
CWE-644 - Improper Neutralization of HTTP Headers for Scripting Syntax
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to improper input validation in HTTP/1 client when handling HTTP Host header. A remote non-authenticated attacker can send a specially crafted HTTP request with a maliciously crafted Host header and inject additional headers or entire requests.
Successful exploitation of the vulnerability may allow an attacker to perform cross-site scripting, cache poisoning or session hijacking attacks.
MitigationInstall updates from vendor's website.

2) Improper Certificate Validation
EUVDB-ID: #VU78913
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-29409
CWE-ID:
CWE-295 - Improper Certificate Validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to verifying certificate chains containing large RSA keys is slow. A remote attacker can cause a client/server to expend significant CPU time verifying signatures.
MitigationInstall updates from vendor's website.

3) Resource exhaustion
EUVDB-ID: #VU82064
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-2023-39325
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 excessive consumption of internal resources when handling HTTP/2 requests. A remote attacker can bypass the http2.Server.MaxConcurrentStreams setting by creating new connections while the current connections are still being processed, trigger resource exhaustion and perform a denial of service (DoS) attack.

4) 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.
