Description

This security bulletin contains information about 8 vulnerabilities.


1) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2021-40528)

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-674 - Uncontrolled Recursion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-254 - Security Features

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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.
