Security Bulletin
This security bulletin contains information about 4 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.

2) Input validation error
EUVDB-ID: #VU83581
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-2023-34055
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in Web Observations. A remote attacker can send specially crafted HTTP requests to the application and perform a denial of service (DoS) attack.
Successful exploitation of the vulnerability requires that application is using Spring MVC or Spring WebFlux and that org.springframework.boot:spring-boot-actuator is on the classpath.

3) 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: Yes
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.
