CVE-2023-50292
Description
A flaw was found in Apache Solr. The Schema Designer was introduced to allow users to more easily configure and test new Schemas and configSets. However, it may load untrusted configSets, which can allow an unauthenticated user to load external libraries when used in the Schema Designer. This issue may allow an attacker to perform remote code execution on the affected system.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert: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 Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
CVSS v3 Score Breakdown
| Red Hat | NVD | cve.org | |
|---|---|---|---|
| Base Score | 6.3 | 7.5 | N/A |
| Attack Vector | Network | Network | N/A |
| Attack Complexity | Low | Low | N/A |
| Privileges Required | Low | None | N/A |
| User Interaction | Required | None | N/A |
| Scope | Unchanged | Unchanged | N/A |
| Confidentiality | High | High | N/A |
| Integrity Impact | Low | None | N/A |
| Availability Impact | None | None | N/A |

Red Hat CVSS v3 Score Explanation
A successful exploit of this flaw requires deliberate use of a configset by a trusted user. Unauthed users cannot achieve an exploit without interaction from an authed user. These two factors are best shown in CVSS evaluation by a Password Required of Low and User Interaction of Required, rather than the preliminary assessment given by NVD. Accordingly, the impact of this flaw is reduced to Moderate.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data; Read Files or Directories
An attacker may be able to read sensitive information from the associated resource, such as credentials or configuration information stored in a file.
Access Control
Technical Impact: Gain Privileges or Assume Identity
An attacker may be able to modify critical properties of the associated resource to gain privileges, such as replacing a world-writable executable with a Trojan horse.
Integrity,Other
Technical Impact: Modify Application Data; Other
An attacker may be able to destroy or corrupt critical data in the associated resource, such as deletion of records from a database.
