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 assess their use of Star Practice Management Web version 2019.2.0.6 and prioritize upgrading to a patched or newer version if available. In the absence of official patches, implement strict network segmentation and access controls to limit exposure of the application to trusted internal networks only. Employ web application firewalls (WAFs) with custom rules to detect and block unauthorized access attempts targeting WIP data endpoints. Conduct thorough access control reviews and audits within the application to ensure user roles and permissions are correctly enforced. Monitor logs for unusual access patterns or attempts to retrieve unauthorized job details. Additionally, consider implementing multi-factor authentication (MFA) for all users to reduce risk from compromised credentials, even though this vulnerability does not require authentication. Regularly update and patch all related infrastructure components and maintain an incident response plan tailored to data confidentiality breaches. Engage with the software vendor or community to obtain updates or workarounds and report any suspicious activity promptly.

Description

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

Impact

For European organizations using Star Practice Management Web 2019.2.0.6, this vulnerability poses a significant risk to the confidentiality of sensitive operational data related to job workflows. Unauthorized access to WIP details could lead to exposure of proprietary business information, client data, or internal project statuses, potentially resulting in competitive disadvantage, reputational damage, or regulatory non-compliance (e.g., GDPR if personal data is involved). Since the vulnerability allows remote exploitation without authentication or user interaction, attackers could leverage this flaw to conduct reconnaissance or data exfiltration stealthily. Healthcare providers, legal firms, or other professional services using this software for practice management may be particularly impacted due to the sensitive nature of their data. The absence of integrity or availability impact means the threat is primarily data exposure rather than disruption or data manipulation. However, the breach of confidentiality alone can have serious consequences under European data protection laws, including fines and mandatory breach notifications.
