Attack Complexity: Low
Attack Vector: Network
Availability: Low
Confidentiality: None
Integrity: Low
Privileges Required: Low
Scope: Unchanged
User Interaction: None

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

Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
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).
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 impacted component 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 impacted component.
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.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.

Exploitation evidence

Disclosed: evidence found.
CVE published 29 Jan 2021
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 first verify if they are running Star Practice Management Web version 2019.2.0.6. In the absence of an official patch, organizations should implement strict access controls to limit user privileges, ensuring that only trusted personnel have any level of access to the application. Monitoring and auditing access to configuration panels should be enhanced to detect unauthorized access attempts promptly. Network segmentation can be used to isolate the management interfaces from general user networks. Additionally, implementing multi-factor authentication (MFA) for all users with any access to the system can reduce the risk of compromised credentials being used to exploit this vulnerability. Organizations should also engage with the vendor or community for updates or patches and apply them promptly once available. Regular security assessments and penetration testing focusing on authorization controls within the application can help identify and remediate similar issues proactively.

Description

An improper authorization vulnerability exists in Star Practice Management Web version 2019.2.0.6, allowing an unauthorized user to access Launcher Configuration Panel.

Impact

For European organizations using Star Practice Management Web 2019.2.0.6, this vulnerability poses a risk of unauthorized configuration changes that could compromise the integrity of their practice management systems. Such systems often handle sensitive patient and operational data, so unauthorized modifications could lead to misconfigurations, data mishandling, or indirect impacts on data security and compliance with regulations such as GDPR. While confidentiality is not directly impacted, integrity compromises can lead to operational disruptions or facilitate further attacks. The requirement for low-level privileges suggests that insider threats or compromised low-privilege accounts could be leveraged to exploit this vulnerability. This risk is particularly relevant for healthcare providers and associated service organizations in Europe, where healthcare data protection is critical and regulated. The absence of known exploits reduces immediate risk but does not eliminate the potential for targeted attacks, especially in environments where this software is widely deployed.
