- Severity: CVSS 5.4 (Medium), CNA
- Vector: CVSS:3.0/A:N/AC:L/AV:N/C:L/I:L/PR:L/S:C/UI:R/E:U/RC:C/RL:O
- Known exploited (CISA KEV): no
- Published: 2018-07-10 · Updated: 2024-09-17

## Affected

- IBM Rational Quality Manager: 5.0, 5.0.1, 5.0.2, 6.0, 6.0.1, 6.0.2, 6.0.3, 6.0.4, 6.0.5

## Description

IBM Rational Quality Manager 5.0 through 5.0.2 and 6.0 through 6.0.5 are vulnerable to HTTP response splitting attacks. A remote attacker could exploit this vulnerability using specially-crafted URL to cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning, cross-site scripting, and possibly obtain sensitive information. IBM X-Force ID: 142658.
