This security bulletin contains information about 4 vulnerabilities.

1) Server-Side Request Forgery (SSRF)

EUVDB-ID: #VU86695

Risk: Medium

CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2024-22243

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input when parsing URL with the UriComponentsBuilder component. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.

Mitigation

Install update from vendor's website.

3) Arbitrary file upload

EUVDB-ID: #VU86635

Risk: Medium

CVSSv4.0: 7.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Green]

CVE-ID: CVE-2023-50386

CWE-ID: CWE-434 - Unrestricted Upload of File with Dangerous Type

Exploit availability: Yes

Description

The vulnerability allows a remote user to compromise vulnerable system.

The vulnerability exists due to Solr ConfigSets accepts Java ".jar" and ".class" files to be uploaded through the ConfigSets API. Such files can be later included into a backup and executed during the restore procedure. When backing up Solr Collections, these configSet files would be saved to disk when using the LocalFileSystemRepository (the default for backups). If the backup was saved to a directory that Solr uses in its ClassPath/ClassLoaders, then the jar and class files would be available to use with any ConfigSet, trusted or untrusted. As a result, a remote user with backup permissions can include malicious files into the backup and execute arbitrary code on the system, when files are restored from the backup.

Mitigation

Install update from vendor's website.
