The vulnerability identified as CVE-2018-7680 affects Micro Focus Solutions Business Manager versions earlier than 11.4, presenting a reflected HTTP header values issue that can be exploited by malicious actors to manipulate or inject data into the application's HTTP responses. This vulnerability stems from insufficient input validation and sanitization within the application's handling of HTTP headers, creating potential attack vectors for various web-based exploits.
The technical flaw manifests when the application fails to properly sanitize or escape HTTP header values before reflecting them back to clients in HTTP responses. This behavior creates an environment where attackers can inject malicious content through crafted HTTP headers, potentially leading to cross-site scripting attacks, session manipulation, or other header-based exploitation techniques. The vulnerability specifically impacts the application's HTTP header processing mechanisms, allowing unauthorized modifications to be reflected back to users without proper validation or encoding.
From an operational impact perspective, this vulnerability can enable attackers to perform various malicious activities including but not limited to session hijacking, credential theft, and client-side code injection. The reflected header values can be manipulated to include malicious JavaScript payloads or other harmful content that executes in the context of the victim's browser, potentially compromising user sessions and data integrity. Organizations using affected versions may experience unauthorized access attempts and potential data breaches through this vector.
Security professionals should implement immediate mitigations including upgrading to Micro Focus Business Manager version 11.4 or later, which contains the necessary patches to address this vulnerability. Additionally, organizations should deploy web application firewalls to monitor and filter suspicious HTTP header values, implement proper input validation mechanisms, and conduct thorough security testing of HTTP header handling components. The vulnerability aligns with CWE-116 for improper encoding or escaping of output and relates to ATT&CK technique T1213 for data from information repositories, emphasizing the need for comprehensive input sanitization and output encoding practices.
The affected application architecture demonstrates a lack of proper HTTP header validation controls, which violates security best practices for web application development. Organizations should establish robust security controls including regular security assessments, input validation frameworks, and secure coding practices to prevent similar vulnerabilities from occurring in other components. Implementing proper HTTP header sanitization and ensuring all reflected values are properly encoded will significantly reduce the attack surface and protect against this specific vulnerability and related exploitation techniques.
