CVE-2022-23541
Public on
Last Modified:
Description
A flaw was found in the jsonwebtoken library. Affected versions of jsonwebtoken library can be misconfigured so that passing a poorly implemented key retrieval function will result in incorrect verification of tokens. Using a different algorithm and key combination in verification than what was used to sign the tokens, specifically, tokens signed with an asymmetric public key could be verified with a symmetric HS256 algorithm. This can lead to the successful validation of forged tokens.

Common Vulnerability Scoring System (CVSS) Score Details
Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authorities (CNA) source for its products and services (see Red Hat classifications ).
| CVSS v3 Score Breakdown | Red Hat | NVD |
|---|---|---|
| CVSS v3 Base Score | 5 | 6.3 |
| Attack Vector | Network | Network |
| Attack Complexity | High | Low |
| Privileges Required | Low | Low |
| User Interaction | None | None |
| Scope | Unchanged | Unchanged |
| Confidentiality Impact | Low | Low |
| Integrity Impact | Low | Low |
| Availability Impact | Low | Low |

Red Hat CVSS v3 Score Explanation
To exploit this vulnerability an authenticated user needs to send a specially crafted request to forge Public/Private Tokens. Hence, AC:H and PR:L. Confidentiality, Integrity, and Availability metrics are Low, because:
- Successful exploitation may lead to some loss of confidentiality, but it's not under attacker's control what information will be obtained.
- Theoretically, an attacker may be able to modify some data but does not have control over the consequences of that modification.
- An attacker is not able to determine if successful exploitation will affect the availability of the target environment.
Frequently Asked Questions
Why is Red Hat's CVSS v3 score or Impact different from other vendors?
For more information, see https://access.redhat.com/solutions/762393.
My product is listed as "Under investigation" or "Affected", when will Red Hat release a fix for this vulnerability?
- "Under investigation" doesn't necessarily mean that the product is affected by this vulnerability. It only means that our Analysis Team is still working on determining whether the product is affected and how it is affected.
- "Affected" means that our Analysis Team has determined that this product is affected by this vulnerability and might release a fix to address this in the near future.
What can I do if my product is listed as "Will not fix"?
Available options depend mostly on the Impact of the vulnerability and the current Life Cycle phase of your product. Overall, you have the following options:
- Upgrade to a supported product version that includes a fix for this vulnerability (recommended).
- Apply a mitigation (if one exists).
- Open a This content is not included.support case to request a prioritization of releasing a fix for this vulnerability.
What can I do if my product is listed as "Fix deferred"?
Available options depend mostly on the Impact of the vulnerability and the current Life Cycle phase of your product. Overall, you have the following options:
- Apply a mitigation (if one exists).
- Open a This content is not included.support case to request a prioritization of releasing a fix for this vulnerability.
- Red Hat Engineering focuses on addressing high-priority issues based on their complexity or limited lifecycle support. Therefore, lower-priority issues will not receive immediate fixes.
What is a mitigation?
I have a Red Hat product but it is not in the above list, is it affected?
Why is my security scanner reporting my product as vulnerable to this vulnerability even though my product version is fixed or not affected?
My product is listed as "Out of Support Scope". What does this mean?
