Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2021-40528)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to use of a broken or risky cryptographic algorithm in the ElGamal implementation. A remote attacker can gain unauthorized access to sensitive information on the system.
2) 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.
3) Use-after-free (CVE-ID: CVE-2023-0215)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the BIO_new_NDEF function. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
4) Uncontrolled Recursion (CVE-ID: CVE-2023-1370)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to uncontrolled recursion when processing nested arrays and objects. A remote attacker can pass specially crafted JSON data to the application and perform a denial of service (DoS) attack.
5) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-27901)
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 within the StaplerRequest. A remote user can initiate a series of uploads and perform a denial of service (DoS) attack.
6) 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.
7) Information disclosure (CVE-ID: CVE-2023-30861)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to missing Vary: Cookie header. A remote attacker can gain unauthorized access to sensitive information on the system.
8) 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.
