Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Deserialization of Untrusted Data (CVE-ID: CVE-2021-46877)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insecure input validation when processing serialized JsonNode values. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
Note, the vulnerability affects JDK serialization only.
2) Deserialization of Untrusted Data (CVE-ID: CVE-2022-1471)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data within the SnakeYaml's Constructor() class. A remote attacker can pass specially crafted yaml content to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Information disclosure (CVE-ID: CVE-2022-31684)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to tge affected applicaton may log request headers in some cases of invalid HTTP requests. A remote user can reveal valid access tokens.
4) Code Injection (CVE-ID: CVE-2022-45143)
The vulnerability allows a remote attacker to manipulate server output.
The vulnerability exists due to improper input validation within the JsonErrorReportValve when handling type, message or description values. A remote attacker can send a specially crafted request and manipulate or invalidate JSON output.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Infinite loop (CVE-ID: CVE-2023-1108)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop caused by an unexpected handshake status updated in SslConduit. A remote attacker can consume all available system resources and cause denial of service conditions.
6) Input validation error (CVE-ID: CVE-2023-20860)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an input validation error caused by using the wildcard ("**") as a pattern in Spring Security configuration with the mvcRequestMatcher, which creates a mismatch in pattern matching between Spring Security and Spring MVC. A remote attacker can bypass certain security restrictions.
7) Input validation error (CVE-ID: CVE-2023-20861)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of SpEL expressions. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
