CVE-2022-44957: n/a in n/a
webtareas 2.4p5 was discovered to contain a cross-site scripting (XSS) vulnerability in the component /clients/listclients.php. This vulnerability allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Name field.
AI Analysis
Technical Summary
CVE-2022-44957 is a medium-severity cross-site scripting (XSS) vulnerability identified in webtareas version 2.4p5, specifically within the /clients/listclients.php component. The vulnerability arises due to insufficient input sanitization of the 'Name' field, allowing an attacker to inject crafted malicious scripts or HTML content. When a victim user accesses the affected page, the injected payload executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) indicates that the attack can be performed remotely over the network with low attack complexity, but requires the attacker to have some privileges (PR:L) and user interaction (UI:R). The vulnerability impacts confidentiality and integrity but does not affect availability. The scope is changed (S:C), meaning the vulnerability can impact resources beyond the initially vulnerable component. No public exploits are currently known, and no official patches have been linked, which suggests that mitigation may rely on configuration or custom fixes. The CWE-79 classification confirms this is a classic reflected or stored XSS issue, a common web application security flaw that can be exploited to compromise user sessions and data integrity.
Potential Impact
For European organizations using webtareas 2.4p5, this vulnerability poses a risk primarily to the confidentiality and integrity of user data. Attackers exploiting this XSS flaw could hijack user sessions, steal sensitive information, or perform unauthorized actions within the application context. This is particularly concerning for organizations managing client data or internal workflows via webtareas, as compromised sessions could lead to data leakage or manipulation. The requirement for some level of privileges and user interaction reduces the likelihood of widespread automated exploitation but does not eliminate risk, especially in environments where users may be targeted via phishing or social engineering. The scope change means that the impact could extend beyond the immediate vulnerable page, potentially affecting other parts of the application or connected systems. Given the lack of known exploits, the threat is currently moderate but could escalate if exploit code becomes publicly available. European entities in sectors such as professional services, client management, or internal task tracking that rely on webtareas should be vigilant, as data privacy regulations like GDPR impose strict requirements on protecting personal data, and breaches could result in significant legal and reputational consequences.
Mitigation Recommendations
Since no official patches are currently available, European organizations should implement the following specific mitigations: 1) Conduct an immediate audit of all user inputs in the /clients/listclients.php page, especially the 'Name' field, to ensure proper input validation and output encoding to neutralize malicious scripts. 2) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the application context, limiting the impact of any injected payloads. 3) Implement strict user privilege management to minimize the number of users with the required privileges (PR:L) to reduce the attack surface. 4) Educate users on the risks of interacting with suspicious links or payloads to mitigate the user interaction requirement. 5) Monitor web application logs for unusual input patterns or repeated attempts to inject scripts. 6) If feasible, isolate the vulnerable component or restrict access to trusted networks until a patch or update is released. 7) Engage with the vendor or community to track patch availability and apply updates promptly once released. 8) Consider deploying web application firewalls (WAF) with custom rules to detect and block typical XSS attack vectors targeting this component.
