Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU82559
Risk: High
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-4886
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote user to compromise the affected system.
The vulnerability exists due to insufficient validation of user-supplied input. A remote user who can create or update ingress objects can use directives to bypass the sanitization of the spec.rules[].http.paths[].path field of an Ingress object (in the networking.k8s.io or extensions API group) to obtain the credentials of the ingress-nginx controller.
Install update from vendor's website.
Vulnerable software versionsIBM InfoSphere Information Server: before 11.7.1.4 Service pack 2

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote authenticated user 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) OS Command Injection
EUVDB-ID: #VU82556
Risk: Medium
CVSSv3.1: 6.8 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2023-5043
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote user to execute arbitrary commands on the target system.
The vulnerability exists due to improper input validation in the nginx.ingress.kubernetes.io/configuration-snippet annotation. A remote user can pass specially crafted data to the application, execute arbitrary OS commands and obtain the credentials of the ingress-nginx controller.

3) Code Injection
EUVDB-ID: #VU82557
Risk: Medium
CVSSv3.1: 6.8 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2023-5044
CWE-ID:
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation in the nginx.ingress.kubernetes.io/permanent-redirect annotation on an Ingress object. A remote user can send a specially crafted request, inject arbitrary commands, and obtain the credentials of the ingress-nginx controller.
MitigationInstall update from vendor's website.
