Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
1) HTTP response splitting
EUVDB-ID: #VU88152
Risk: Medium
CVSSv3.1: 6.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2024-24795
CWE-ID:
CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform HTTP splitting attacks.
The vulnerability exists due to software does not correctly process CRLF character sequences in multiple modules. A remote attacker can inject malicious response headers into backend applications and perform an HTTP desynchronization attack.
Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.

3) HTTP response splitting
EUVDB-ID: #VU88151
Risk: Medium
CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-38709
CWE-ID:
CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform HTTP splitting attacks.
The vulnerability exists due to software does not correctly process CRLF character sequences. A malicious or exploitable backend/content generators can send specially crafted response containing CRLF sequence and make the application to send a split HTTP response.
Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.
