CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N

Attack Vector: Network
Attack Complexity: Low
Privileges Required: None
User Interaction: None
Scope: Changed
Confidentiality: None
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: 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: 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 16 Jul 2025
Detectable: no evidence on record.
No public nuclei template indexed

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

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 this vulnerability, European organizations should prioritize the following actions: 1) Immediate deployment of any available patches or updates from Cisco for the affected versions of Cisco Unified Contact Center Express. If patches are not yet available, implement temporary mitigations such as restricting access to the web-based management interface to trusted internal networks only, using network segmentation and firewall rules to limit exposure. 2) Implement strict input validation and filtering at network perimeter devices to detect and block suspicious HTTP requests that could exploit SSRF. 3) Monitor network traffic originating from Cisco Unified Contact Center Express devices for unusual outbound requests to internal or external resources that could indicate exploitation attempts. 4) Conduct thorough audits of internal network services accessible from the contact center devices to ensure minimal exposure and enforce least privilege principles. 5) Employ multi-factor authentication and strong access controls on management interfaces to reduce risk from other attack vectors. 6) Prepare incident response plans that include detection and containment strategies for SSRF exploitation scenarios. These steps go beyond generic advice by focusing on network-level controls, monitoring, and access restrictions tailored to the affected product and vulnerability characteristics.

Description

A vulnerability in the web-based management interface of Cisco Unified Intelligence Center could allow an unauthenticated, remote attacker to conduct a server-side request forgery (SSRF) attack through an affected device. This vulnerability is due to improper input validation for specific HTTP requests. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to send arbitrary network requests that are sourced from the affected device.

Impact

For European organizations, the impact of this SSRF vulnerability can be substantial. Cisco Unified Contact Center Express is commonly deployed in customer service and call center environments, which are critical for business continuity and customer satisfaction. Exploitation could allow attackers to bypass network segmentation by leveraging the vulnerable device to send requests to internal systems, potentially exposing sensitive internal services, configuration endpoints, or management interfaces that are not directly accessible from the internet. This could lead to further lateral movement, data integrity issues, or unauthorized access to internal resources. Given the unauthenticated nature of the exploit, attackers do not need valid credentials, increasing the risk of opportunistic attacks. The integrity impact could manifest as manipulation or disruption of internal communications or data flows. While availability and confidentiality impacts are rated as none or low, the ability to manipulate internal requests can indirectly affect service reliability and trustworthiness. European organizations in sectors such as finance, telecommunications, and public services that rely heavily on Cisco contact center solutions are particularly at risk, as disruption or compromise of these systems could affect critical customer interactions and regulatory compliance.
