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: 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

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 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 access to the /api/system/dashboard/getCount endpoint by implementing network-level controls such as IP whitelisting or VPN-only access to the CyreneAdmin interface. 2. Employ strong authentication and authorization mechanisms around all API endpoints, ensuring that only authorized users can access sensitive system information. 3. Monitor API logs for unusual or unauthorized access patterns targeting the affected endpoint to detect potential exploitation attempts early. 4. Engage with CoCoTeaNet to obtain official patches or updates addressing this vulnerability and apply them promptly once available. 5. If patches are not yet available, consider deploying web application firewalls (WAFs) or API gateways with custom rules to block unauthorized requests to the vulnerable endpoint. 6. Conduct regular security assessments and penetration testing focused on API authorization controls to identify and remediate similar issues proactively. 7. Educate system administrators and security teams about this vulnerability and the importance of securing administrative interfaces against unauthorized access.

Description

A vulnerability was determined in CoCoTeaNet CyreneAdmin up to 1.3.0. This vulnerability affects unknown code of the file /api/system/dashboard/getCount of the component System Info Endpoint. Executing a manipulation can lead to improper authorization. The attack can be launched remotely. The exploit has been publicly disclosed and may be utilized.

Impact

The primary impact of CVE-2026-2693 is unauthorized access to system information via the CyreneAdmin dashboard API, which could compromise confidentiality by exposing sensitive operational data. This information leakage can facilitate attackers' reconnaissance efforts, enabling them to identify system configurations, user counts, or other metrics that may assist in crafting more targeted attacks. While the vulnerability does not directly affect system integrity or availability, the unauthorized access could serve as a stepping stone for privilege escalation or lateral movement within an organization's network. Organizations relying on CyreneAdmin for system administration and monitoring may face increased risk of data exposure and potential compromise. The medium severity suggests that while immediate catastrophic damage is unlikely, the vulnerability still poses a meaningful threat, especially in environments with sensitive or critical infrastructure. The lack of authentication requirement and remote exploitability increase the attack surface and risk profile for exposed deployments.

Summary

CVE-2026-2693 identifies an improper authorization vulnerability in CoCoTeaNet's CyreneAdmin product, versions 1.0 through 1.3.0. The vulnerability resides in the System Info Endpoint, specifically the /api/system/dashboard/getCount API, where insufficient authorization checks allow remote attackers to access or manipulate system information without proper privileges. The attack vector is network-based (AV:N), requires low attack complexity (AC:L), and does not require authentication (PR:L) or user interaction (UI:N). The vulnerability impacts confidentiality moderately (VC:L) but does not affect integrity or availability. The improper authorization could enable attackers to gather sensitive system metrics or information that should be restricted, potentially aiding further attacks such as privilege escalation or lateral movement. Although no known exploits are currently active in the wild, the public disclosure of exploit details increases the likelihood of exploitation attempts. The vulnerability's medium severity rating (CVSS 5.3) reflects its moderate impact and ease of exploitation. No official patches have been linked yet, indicating that affected organizations must rely on interim mitigations until vendor updates are released.
