Threat metrics

Exploit Maturity: POC

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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system 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 Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 15 Nov 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
Observed by OffSeq MirageSeen by Mirage: 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 2026-10-26.

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

1. Immediately restrict network access to the /xml/sistema/usuarios.xml file and related UnniTI management interfaces using firewall rules, VPNs, or network segmentation to limit exposure to trusted internal networks only. 2. Monitor network traffic and logs for unusual access patterns or attempts to manipulate the Usuario/Senha argument, employing intrusion detection/prevention systems tuned for this vulnerability. 3. Rotate all credentials stored or managed by UnniTI regularly, especially if exposure is suspected or confirmed, to limit the window of compromise. 4. Implement multi-factor authentication (MFA) on systems that integrate with or rely on UnniTI to reduce the impact of credential theft. 5. Engage with Intelbras for timely patch releases and apply security updates as soon as they become available. 6. Conduct a thorough audit of all systems using UnniTI to identify and isolate vulnerable instances. 7. Educate IT and security teams about this vulnerability and the importance of safeguarding credential storage and access controls. 8. Consider deploying endpoint detection and response (EDR) solutions to detect lateral movement attempts post-exploitation.

Description

A weakness has been identified in Intelbras UnniTI 24.07.11. The affected element is an unknown function of the file /xml/sistema/usuarios.xml. Executing manipulation of the argument Usuario/Senha can lead to unprotected storage of credentials. The attack can be executed remotely. The exploit has been made available to the public and could be exploited.

Impact

For European organizations, the unprotected storage of credentials in Intelbras UnniTI can lead to unauthorized access to critical systems if attackers retrieve and reuse these credentials. This can compromise confidentiality and potentially enable lateral movement within networks, increasing the risk of data breaches and operational disruption. Sectors such as telecommunications, manufacturing, and critical infrastructure that rely on Intelbras products may face heightened risks. Credential exposure can also facilitate supply chain attacks or insider threats if attackers gain persistent access. The remote exploitability without authentication broadens the attack surface, making organizations with externally accessible UnniTI instances particularly vulnerable. Additionally, the availability of a public exploit increases the likelihood of opportunistic attacks. European data protection regulations, including GDPR, impose strict requirements on protecting personal and sensitive data, and exploitation of this vulnerability could lead to regulatory penalties and reputational damage. Organizations may also face increased costs related to incident response, forensic investigations, and remediation.
