Integrity: Low
Availability: None

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: 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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: no evidence on record.

No attack traffic recorded by OffSeq Mirage sensors

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.

What to do

AI-suggested

1. Immediately restrict network access to Passwordstate Core interfaces, limiting exposure to trusted internal networks only. 2. Implement strict firewall rules and VPN requirements to control remote access. 3. Monitor logs and network traffic for unusual authentication bypass attempts or unauthorized access patterns. 4. Enforce multi-factor authentication (MFA) on all administrative and user accounts interacting with Passwordstate, if supported, to add an additional security layer. 5. Regularly audit user accounts and permissions within Passwordstate to detect and remove any unauthorized changes. 6. Stay alert for official patches or updates from Click Studios and apply them promptly once available. 7. Consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious authentication bypass attempts. 8. Conduct internal penetration testing and vulnerability assessments focused on Passwordstate deployments to identify any exploitation attempts. 9. Educate IT and security teams about this vulnerability and prepare incident response plans in case of compromise. 10. If feasible, isolate Passwordstate servers in segmented network zones to reduce lateral movement risk.

Click Studios Passwordstate Core before 9.8 build 9858 allows Authentication Bypass.

Impact

The primary impact of CVE-2024-39337 is unauthorized access to sensitive password management data, which can lead to credential theft, lateral movement within networks, and potential compromise of multiple systems. Confidentiality is at risk because attackers bypass authentication to access stored passwords. Integrity is also impacted as attackers could modify or delete password entries, disrupting security operations. Although availability is not directly affected, the indirect consequences of compromised credentials could lead to broader system outages or data breaches. The ease of exploitation—no authentication or user interaction required—raises the risk level, especially for organizations exposing Passwordstate Core interfaces to untrusted networks. This vulnerability could facilitate advanced persistent threats (APTs) or insider threats gaining elevated access. The lack of known exploits in the wild currently limits immediate widespread impact, but the potential for rapid exploitation once details become public is significant. Organizations worldwide using affected versions face risks of credential compromise and subsequent attacks on critical infrastructure and data.
