Multiple vulnerabilities in IBM Watson Discovery

1) Memory leak

EUVDB-ID: #VU87830

Risk: Medium

CVSSv4.0: 6.6 [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]

CVE-ID: CVE-2024-1394

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak in the RSA encrypting/decrypting code when handling untrusted input. A remote attacker can pass specially crafted data to the application and perform denial of service attack.

Mitigation

Install update from vendor's website.

3) Input validation error

EUVDB-ID: #VU83254

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-45284

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a local user to bypass implemented security restrictions.

The vulnerability exists due to the IsLocal() function from the path/filepath package does not correctly detect reserved device names in some cases when executed on Windows. Reserved names followed by spaces, such as "COM1 ", and reserved names "COM" and "LPT" followed by superscript 1, 2, or 3, are incorrectly reported as local. A local user can abuse such behavior and bypass implemented security restrictions.

Mitigation

Install update from vendor's website.
