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: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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.

What to do

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Description

An authentication bypass in Ivanti Endpoint Manager before version 2024 SU5 allows a remote unauthenticated attacker to leak specific stored credential data.

Impact

The primary impact of CVE-2026-1603 is the unauthorized disclosure of stored credential data within Ivanti Endpoint Manager. This can lead to significant confidentiality breaches, enabling attackers to escalate privileges, move laterally within networks, or compromise additional systems using leaked credentials. Since the vulnerability does not affect integrity or availability directly, the immediate operational disruption may be limited. However, the exposure of credentials can facilitate subsequent attacks such as privilege escalation, data exfiltration, or ransomware deployment. Organizations relying on Ivanti Endpoint Manager for endpoint security and management may face increased risk of compromise, especially in environments where credential reuse or weak credential management practices exist. The fact that exploitation requires no authentication or user interaction increases the threat level, as attackers can remotely target vulnerable systems without insider access or social engineering. This vulnerability could be particularly damaging in large enterprises, managed service providers, and critical infrastructure sectors where Ivanti Endpoint Manager is deployed to manage numerous endpoints and sensitive assets.

Mitigation

1. Apply patches or updates from Ivanti as soon as they become available for Endpoint Manager 2024 SU5 or later versions that address this vulnerability. 2. Until patches are released, restrict network access to the Ivanti Endpoint Manager interface by implementing network segmentation and firewall rules to limit exposure to trusted management networks only. 3. Monitor network traffic and logs for unusual access patterns or attempts to exploit authentication mechanisms, focusing on remote unauthenticated access attempts. 4. Enforce strong credential management policies, including the use of unique, complex passwords and multi-factor authentication where supported, to reduce the impact of leaked credentials. 5. Conduct regular security assessments and penetration testing on endpoint management infrastructure to identify and remediate potential weaknesses. 6. Educate IT and security teams about this vulnerability and ensure incident response plans include steps to detect and respond to potential exploitation. 7. Consider deploying additional endpoint detection and response (EDR) solutions to identify suspicious activity related to credential theft or lateral movement.
