Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) 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.
MitigationInstall updates from vendor's website.
Vulnerable software versionsApache HTTP Server: 2.0 - 2.4.58
External linkshttp://downloads.apache.org/httpd/CHANGES_2.4
http://httpd.apache.org/security/vulnerabilities_24.html
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) 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.
MitigationInstall updates from vendor's website.

3) Resource exhaustion
EUVDB-ID: #VU88153
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-2024-27316
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 application does not properly control consumption of internal resources when handling HTTP/2 requests. A remote attacker can send specially crafted HTTP/2 requests to the server and perform a denial of service (DoS) attack.
MitigationInstall updates from vendor's website.
