Attack Vector: Network
Attack Complexity: Low
Privileges Required: None
User Interaction: None
Scope: Changed
Confidentiality: None
Integrity: High
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: 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: None: There is no loss of confidentiality within the impacted component.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Oct 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

European organizations should immediately verify if they are running affected versions of Junos Space Security Director and prioritize upgrading to version 24.1R3 Patch V4 or later, where the vulnerability is fixed. Until patching is complete, restrict network access to the Junos Space Security Director web interface by implementing strict firewall rules, VPN access, or network segmentation to limit exposure to trusted administrators only. Enable and monitor detailed logging of administrative actions and metadata changes to detect suspicious activity. Conduct regular audits of firewall policies on managed SRX devices to identify unauthorized modifications. Employ intrusion detection systems to alert on anomalous traffic patterns that may indicate policy bypass attempts. Additionally, review and enhance overall network access controls and multi-factor authentication for management interfaces to reduce risk from other potential attack vectors.

Description

A Missing Authorization vulnerability in the Juniper Networks Junos Space Security Director allows an unauthenticated network-based attacker to read or modify metadata via the web interface. Tampering with this metadata can result in managed SRX Series devices permitting network traffic that should otherwise be blocked by policy, effectively bypassing intended security controls. This issue affects Junos Space Security Director * all versions prior to 24.1R3 Patch V4 This issue does not affect managed cSRX Series devices.

Impact

For European organizations, this vulnerability poses a significant risk to network security integrity. Successful exploitation can allow attackers to bypass firewall policies, potentially enabling unauthorized access to sensitive internal resources, lateral movement, or data exfiltration. Critical infrastructure, financial institutions, telecommunications providers, and government agencies using Junos Space Security Director to manage SRX firewalls could face increased exposure to cyberattacks. The lack of authentication requirement and network accessibility of the web interface heighten the risk of remote exploitation. This could lead to regulatory compliance violations under GDPR if personal data is exposed or compromised due to weakened network defenses. The disruption of security controls may also impact operational continuity and trust in managed network environments.
