Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) LDAP injection
EUVDB-ID: #VU78328
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-2023-33201
CWE-ID:
CWE-90 - Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to improper input validation in applications that use an LDAP CertStore from Bouncy Castle to validate X.509 certificates. During the certificate validation process, Bouncy Castle inserts the certificate's Subject Name into an LDAP search filter without any escaping, which leads to an LDAP injection vulnerability. A remote non-authenticated attacker can use a specially crafted X.509 certificate to bypass authentication process and gain unauthorized access to the application.
MitigationInstall 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 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) Resource exhaustion
EUVDB-ID: #VU85874
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-2023-33202
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 parsing OpenSSL PEM encoded streams containing X.509 certificates. A remote attacker can send ASN.1 data through the PEMParser to trigger resource exhaustion and perform a denial of service (DoS) attack.
