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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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: 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 to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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 8 Feb 2026
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 2026-10-25.

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

1. Immediately identify and inventory all UTT HiPER 810 devices running version 1.7.4-141218 within the network. 2. Engage with the vendor UTT to obtain official patches or firmware updates addressing CVE-2026-2135. 3. If patches are unavailable, implement network-level access controls to restrict access to the /goform/formPdbUpConfig endpoint, limiting it to trusted management networks only. 4. Employ web application firewalls (WAFs) or intrusion prevention systems (IPS) with custom rules to detect and block suspicious inputs targeting the policyNames parameter. 5. Monitor device logs and network traffic for anomalous commands or unexpected behavior indicative of exploitation attempts. 6. Consider isolating affected devices in segmented network zones to minimize lateral movement risks. 7. Educate network administrators about the vulnerability and the importance of restricting remote management interfaces. 8. Regularly review and update device configurations to follow security best practices, minimizing exposed attack surfaces.

Description

A vulnerability was detected in UTT HiPER 810 1.7.4-141218. The impacted element is the function sub_43F020 of the file /goform/formPdbUpConfig. Performing a manipulation of the argument policyNames results in command injection. It is possible to initiate the attack remotely. The exploit is now public and may be used.

Impact

The exploitation of CVE-2026-2135 can lead to unauthorized remote command execution on UTT HiPER 810 devices, potentially allowing attackers to alter device configurations, disrupt network operations, or use the compromised device as a foothold for further network intrusion. This can degrade the availability and integrity of the device and connected systems, possibly causing service interruptions or data manipulation. Organizations relying on these devices for critical network functions or industrial control may face operational disruptions. The public availability of an exploit increases the likelihood of opportunistic attacks, especially in environments where devices are exposed to untrusted networks. Although the vulnerability does not require authentication, the impact on confidentiality is limited, but integrity and availability risks are more pronounced. The scope of affected systems is limited to the specific device and version, but given the device's deployment in certain sectors, the impact can be significant for targeted organizations.
