Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate CVE-2025-36249, organizations should immediately verify and enforce that all session cookies in IBM Jazz for Service Management have the 'Secure' attribute set, ensuring cookies are only transmitted over HTTPS. This may require configuration changes or updates once IBM releases patches. In the interim, enforce strict HTTPS usage by redirecting all HTTP requests to HTTPS and disabling HTTP access to the service management portal. Implement HTTP Strict Transport Security (HSTS) headers to prevent protocol downgrade attacks. Educate users to avoid clicking on HTTP links related to IBM Jazz and to report suspicious URLs. Network-level controls such as blocking outbound HTTP traffic to the service management domain can also reduce risk. Regularly monitor network traffic for unencrypted cookie transmissions and review logs for unusual session activity. Finally, maintain up-to-date software versions and apply IBM patches promptly when available to address this and other vulnerabilities.

Description

IBM Jazz for Service Management 1.1.3.0 through 1.1.3.25 does not set the secure attribute on authorization tokens or session cookies. Attackers may be able to get the cookie values by sending a http:// link to a user or by planting this link in a site the user goes to. The cookie will be sent to the insecure link and the attacker can then obtain the cookie value by snooping the traffic.

Impact

For European organizations using IBM Jazz for Service Management, this vulnerability could lead to unauthorized disclosure of session cookies if users are tricked into visiting HTTP links. The primary impact is confidentiality loss, potentially enabling attackers to hijack user sessions and gain unauthorized access to service management functions. This could disrupt IT service operations, expose sensitive management data, or allow attackers to manipulate service workflows. However, the impact is limited by the high complexity of attack execution and the requirement that users access insecure HTTP links. Organizations with strict network segmentation or HTTPS enforcement may be less affected. Still, environments where users access IBM Jazz from untrusted networks or where HTTP links are common pose a higher risk. The vulnerability does not affect system integrity or availability directly but could be a stepping stone for further attacks if exploited. Given the critical role of service management platforms in IT operations, even low-severity vulnerabilities warrant timely remediation to maintain operational security.
