CVE-2026-4820 identifies a security weakness in IBM Maximo Application Suite versions 8.10, 8.11, 9.0, and 9.1 where authorization tokens and session cookies do not have the 'Secure' attribute set. The 'Secure' attribute instructs browsers to only send cookies over HTTPS connections, preventing exposure over unencrypted HTTP. Without this attribute, if a user accesses a malicious or crafted HTTP link, the browser will transmit these sensitive cookies in plaintext over the network. An attacker positioned on the same network or controlling a malicious site can intercept these cookies by sniffing network traffic, potentially enabling session hijacking or unauthorized access. The vulnerability is classified under CWE-614, which concerns sensitive cookies transmitted without the 'Secure' flag. The CVSS 3.1 base score is 4.3 (medium), reflecting the attack vector as network, low attack complexity, no privileges required, but requiring user interaction. The impact is limited to confidentiality loss, with no direct impact on integrity or availability. No patches or exploits are currently documented, but the risk remains significant for environments where users might be tricked into visiting HTTP links. This vulnerability highlights the importance of secure cookie attributes in web application security, especially for enterprise software managing critical assets like IBM Maximo.

The primary impact of this vulnerability is the potential compromise of session confidentiality. Attackers can intercept session cookies if users access HTTP links, enabling session hijacking or unauthorized access to the IBM Maximo Application Suite. This can lead to unauthorized viewing or manipulation of asset management data, potentially disrupting business operations or exposing sensitive information. While the vulnerability does not directly affect data integrity or system availability, the breach of session tokens can facilitate further attacks or unauthorized actions within the application. Organizations with remote or mobile users who might access links over insecure networks are particularly at risk. The lack of the 'Secure' attribute increases exposure in environments where HTTPS enforcement is not strict or users are susceptible to phishing or social engineering attacks. Overall, the vulnerability undermines trust in session security and could lead to data leakage or compliance violations in regulated industries.

To mitigate CVE-2026-4820, organizations should immediately verify and enforce that all session cookies and authorization tokens in IBM Maximo Application Suite are set with the 'Secure' attribute. This can be done by applying any available patches from IBM or, if patches are not yet available, by configuring the web server or application settings to add the 'Secure' flag to cookies. Additionally, organizations should enforce HTTPS usage across all user access points via HTTP Strict Transport Security (HSTS) headers to prevent users from accessing the application over HTTP. User education on avoiding clicking unknown HTTP links and implementing network-level protections such as TLS inspection and intrusion detection can further reduce risk. Monitoring network traffic for unencrypted cookie transmissions and anomalous session activities can help detect exploitation attempts. Finally, reviewing and updating session management policies to include secure cookie attributes and regular security assessments of web applications are recommended best practices.
