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

Attack Complexity: Low
Attack Vector: Network
Availability: None
Confidentiality: High
Integrity: None
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: None: There is no impact to availability within the impacted component.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within 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
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

Organizations should immediately verify if they are running Star Practice Management Web version 2019.2.0.6 and restrict access to the Audit Trail feature to only trusted and authorized personnel. Implement strict role-based access control (RBAC) policies and audit user permissions regularly to ensure no unauthorized accounts have access to sensitive job details. Network segmentation and application-layer firewalls can help limit exposure of the management web interface to trusted networks or VPN users only. Monitoring and logging access to the Audit Trail feature should be enhanced to detect anomalous or unauthorized access attempts. If a patch or update is available from the vendor, it should be applied promptly. In the absence of an official patch, consider disabling or restricting the Audit Trail feature until a fix is released. Additionally, conduct user awareness training to mitigate risks from compromised credentials and enforce strong authentication mechanisms, such as multi-factor authentication (MFA), to reduce the likelihood of unauthorized access.

Description

An improper authorization vulnerability exists in Star Practice Management Web version 2019.2.0.6, allowing an unauthorized user to access details about jobs he should not have access to via the Audit Trail Feature.

Impact

For European organizations using Star Practice Management Web 2019.2.0.6, this vulnerability could lead to unauthorized disclosure of sensitive job-related information, potentially including client data, internal workflows, or audit logs. This exposure could result in privacy violations, regulatory non-compliance (e.g., GDPR), and reputational damage. Since the vulnerability allows unauthorized access without user interaction and requires only low privileges, it increases the risk of insider threats or external attackers exploiting compromised accounts to escalate data exposure. The confidentiality breach could facilitate further targeted attacks or social engineering campaigns. While the vulnerability does not affect system integrity or availability, the leakage of sensitive information can have significant operational and legal consequences for healthcare or professional service providers relying on this software in Europe.
