Security Bulletin
Summary
The Jose4j library is vulnerable to a denial of service, caused by improper input validation. It could also allow a remote attacker to obtain sensitive information using cryptographic attacks.
Vulnerability Details
CVEID: CVE-2023-31582
DESCRIPTION: Jose4J could allow a remote attacker to obtain sensitive information, caused by allowing of a low iteration count of 1000 or less. By utilize cryptographic attack techniques, an attacker could exploit this vulnerability to obtain hashed password values, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/269733 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2023-51775
DESCRIPTION: jose4j is vulnerable to a denial of service, caused by improper input validation. By sending a specially crafted p2c value, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/275907 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
IBM X-Force ID: 254437
DESCRIPTION: Jose4J could allow a remote attacker to obtain sensitive information, caused by a chosen ciphertext attack in RSA1_5. By using cryptographic attack techniques, an attacker could exploit this vulnerability to decrypt RSA1_5 or RSA_OAEP encrypted ciphertexts.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/254437 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
IBM X-Force ID: 186425
DESCRIPTION: The jose.4.j library could allow a remote attacker to obtain sensitive information, caused by an Elliptic Curve Key Disclosure if the JWK's Header Parameter includes the public key. An attacker could generate a private key/public key pair and send the public key together with the signature resulting in the invalidation of the signature.
CVSS Base score: 8.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/186425 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:N)

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
