Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Security features bypass (CVE-ID: CVE-2023-20862)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the logout support does not properly clean the security context if using serialized versions. A remote attacker can save an empty security context to the HttpSessionSecurityContextRepository and keep users authenticated even after they performed logout.
2) Information disclosure (CVE-ID: CVE-2022-43928)
The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote user can utilize a Java string for processing to gain unauthorized access to sensitive information on the system.
3) Stack-based buffer overflow (CVE-ID: CVE-2022-45688)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists in the XML.toJSONObject component. A remote unauthenticated attacker can send a specially crafted JSON or XML data, trigger stack-based buffer overflow and perform a denial of service attack.
4) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-24998)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to Apache Commons FileUpload does not limit the number of request parts. A remote attacker can initiate a series of uploads and perform a denial of service (DoS) attack.
5) Out-of-bounds write (CVE-ID: CVE-2022-41854)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a boundary error when parsing untrusted YAML files. A remote attacker can send a specially crafted YAML file, trick the victim into opening it using the affected software, trigger out-of-bounds write and perform a denial of service attack.
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) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2023-20859)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to software stores sensitive information into log files when application attempts to revoke a Vault batch token. A local user can read the log files and gain access to sensitive data.
8) 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.
9) Input validation error (CVE-ID: CVE-2023-20863)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote user can use a specially crafted SpEL expression and perform a denial of service (DoS) attack.
