The vulnerability identified as CVE-2011-4818 represents a critical open redirect flaw within IBM Maximo Asset Management and Asset Management Essentials versions 6.2, 7.1, and 7.5. This security weakness resides in the application's handling of user sessions and redirects, specifically through the uisessionid parameter that is processed by an unspecified component within the system architecture. The vulnerability enables authenticated attackers to manipulate the redirect functionality and potentially direct users to malicious web addresses, creating a significant risk for enterprise environments that rely on these asset management solutions for critical business operations.
The technical implementation of this flaw involves the improper validation and sanitization of the uisessionid parameter which is used to maintain user sessions and facilitate navigation within the Maximo application. When an authenticated user interacts with the vulnerable component, the system fails to adequately verify the destination URL before performing a redirect operation. This allows an attacker who has gained valid credentials to craft malicious URLs containing crafted uisessionid values that point to attacker-controlled domains. The vulnerability specifically affects the session management and navigation components of the Maximo platform, which are integral to maintaining user context and application flow throughout the asset management workflow.
From an operational perspective, this vulnerability poses substantial risks to organizations utilizing IBM Maximo solutions, as it can be exploited to conduct sophisticated phishing attacks against legitimate users. Attackers can leverage this weakness to redirect authenticated users to malicious websites that mimic the legitimate Maximo interface, potentially capturing credentials or other sensitive information. The impact extends beyond simple redirection since authenticated users are already trusted by the system, making the phishing attacks more convincing and potentially more successful. Organizations may experience unauthorized access to sensitive asset data, disruption of business processes, and potential data exfiltration through these malicious redirections.
The vulnerability aligns with CWE-601 Open Redirect vulnerability classification, which specifically addresses situations where applications redirect users to external domains without proper validation, and maps to ATT&CK technique T1566.001 Phishing with Spoofed Credentials where attackers use legitimate-looking redirects to deceive users. Organizations should implement immediate mitigations including input validation of the uisessionid parameter, implementation of strict URL validation mechanisms, and regular security updates to address this vulnerability. The recommended approach involves configuring the application to only allow redirects to pre-approved domains or implementing a whitelist of acceptable redirect destinations, while also ensuring that session management components properly validate all redirect targets before execution. Additionally, network-level controls and web application firewalls can provide additional layers of protection against exploitation attempts targeting this specific vulnerability.
