CVE-2018-2015 in API Connect
Summary
by MITRE
IBM API Connect 2018.1 and 2018.4.1.4 could allow a remote attacker to hijack the clicking action of the victim. By persuading a victim to visit a malicious Web site, a remote attacker could exploit this vulnerability to hijack the victim's click actions and possibly launch further attacks against the victim. IBM X-Force ID: 155195.

This vulnerability in IBM API Connect versions 2018.1 and 2018.4.1.4 represents a sophisticated clickjacking attack vector that exploits the web application's lack of proper security controls. The flaw allows remote attackers to manipulate user interactions by overlaying invisible or transparent elements on top of legitimate web interface components, effectively hijacking user click actions. This type of vulnerability falls under the CWE-1021 category of "Improper Restriction of Rendered UI Layers or Frames" and aligns with ATT&CK technique T1059.007 for User Execution through Web-based Attack. The vulnerability specifically targets the application's user interface rendering mechanisms, where proper framebusting and click protection measures are insufficient or absent.
The technical implementation of this vulnerability involves the exploitation of insufficient security controls in the web application's user interface components. Attackers can craft malicious web pages that contain transparent iframes or overlay elements designed to capture user clicks intended for legitimate application interfaces. When victims navigate to these malicious sites, the attacker's page can intercept and redirect user interactions, potentially allowing unauthorized actions to be performed on behalf of the victim. This creates a dangerous scenario where users believe they are interacting with legitimate application components while unknowingly executing actions controlled by the attacker. The vulnerability essentially breaks the principle of least privilege by allowing unauthorized manipulation of user interface interactions.
The operational impact of this vulnerability extends beyond simple session hijacking, as it provides attackers with a foundation for launching more sophisticated attacks. Once click hijacking is established, attackers can potentially harvest sensitive information, perform unauthorized transactions, or escalate privileges within the application. The vulnerability particularly affects enterprise users who may be accessing the API Connect management interfaces, as these interfaces often contain administrative functions that could be exploited. The attack vector requires social engineering to convince victims to visit malicious sites, but once successful, it can provide persistent access to the application's functionality. This vulnerability impacts the integrity and availability of the application's user interface security controls, potentially leading to complete compromise of the system's administrative functions.
Organizations should implement comprehensive mitigations including the deployment of Content Security Policy headers, frame-busting scripts, and proper X-Frame-Options settings to prevent the embedding of application interfaces in malicious contexts. The implementation of clickjacking protection mechanisms such as the use of the frame-ancestors directive in CSP headers can effectively prevent the vulnerability from being exploited. Additionally, regular security assessments and user education programs should be implemented to reduce the risk of successful social engineering attacks that leverage this vulnerability. The remediation process should involve updating to patched versions of IBM API Connect, implementing proper security headers, and conducting thorough security testing of all web interfaces to ensure that similar vulnerabilities are not present in other components of the system. These measures align with security best practices outlined in NIST SP 800-53 and ISO 27001 standards for web application security controls.
