CVE Vulnerability Catalog

A flaw was found in Moodle where user list filters do not properly enforce visibility restrictions on user profile fields. An authorized user with manager privileges can filter user lists using profile attributes they are not permitted to view directly, resulting in unauthorized information disclosure by inferring hidden user data.

In Moodle, insufficient sanitization of username input on the password reset page allows a remote attacker to conduct a cross-site scripting (XSS) attack. By convincing an unauthenticated user to access a specially crafted password reset link, an attacker could execute arbitrary script in the victim's browser.

In Moodle, when enrolling a user into a course while assigning them to a group, the application does not verify whether the selected group actually belongs to that course. An authenticated user with teacher privileges could exploit this flaw to add users to groups within courses they do not have authorization to access.

In Moodle, due to a missing capability check, a low-privileged authenticated user can trigger the recalculation of grade penalties without holding the required permissions. This issue allows unauthorized users to modify grade penalty records, potentially altering student assessment scores.

A flaw was found in Moodle where an incorrect capability check in the AI editor placement's image generation web service allows an authenticated user to invoke the feature without holding the required capability. This flaw permits unauthorized users to access and utilize the AI image generation functionality.

A flaw was found in Moodle where the manual enrolment management page did not properly check whether the manual enrolment plugin was disabled, allowing users with enrolment permissions to access the page directly by navigating to its URL. Consequently, an authorized user could manage manual enrolments even after an administrator disabled the feature in the user interface.

In Moodle, insufficient output escaping in templates used to display forum posts enables a stored cross-site scripting (XSS) vulnerability. An attacker can inject malicious content into a forum post, which then executes arbitrary script code in the browser of another user viewing the affected post.

A flaw was found in Moodle that allows an authenticated attacker to supply an improperly validated audience class name to the Report Builder component, enabling arbitrary class instantiation. This vulnerability enables unauthorized creation of internal program objects, which may result in unexpected application behavior.

In Moodle, an incorrect capability check in the grade web service allows an authenticated student to access profile information of other students enrolled in the same course that they should not have permission to view. This issue leads to unauthorized information disclosure.

In Moodle, an authenticated attacker with access to the question bank web service can submit unsanitized input directly into database queries, resulting in a SQL injection vulnerability. This issue could allow an attacker to view, alter, or delete sensitive data stored in the underlying database.

In Moodle, incorrect handling of IPv4-mapped IPv6 addresses within the URL downloader's host-blocking logic allows an authenticated remote user to bypass blocked-host restrictions. By supplying a crafted URL, an attacker can induce the server to make requests to restricted destinations, leading to Server-Side Request Forgery (SSRF).

A vulnerability in the Go implementation of Apache PLC4X (PLC4Go) involves improper verification of the source of a communication channel during ADS discovery. An attacker can send a spoofed UDP datagram to the discovering host, redirecting subsequent connections to an arbitrary address. The connection address is derived from the AmsNetId in the response body rather than the datagram's actual source. Additionally, a single malformed datagram can disable discovery listeners in both PLC4Go and PLC4J implementations, causing panics, exceptions, or infinite loops.

The Go implementation of Apache PLC4X (PLC4Go) contains multiple severe defects, including integer overflow, improper validation of array indices, uncontrolled recursion, and memory allocation with excessive size values. A malicious device or an attacker able to inject network traffic can crash or exhaust the memory of the client application, causing a denial of service.

A vulnerability in Apache PLC4X (Java implementation, PLC4J) allows a malicious or impersonated device to exhaust the memory or stack of the client application, causing a denial of service. In the OPC UA driver, these defects are reachable before authentication, during secure channel and session establishment, before the server's identity is bound. Affects versions 0.10.0 through 0.13.1.

EasyFlow .NET developed by Digiwin has a Reflected Cross-site Scripting vulnerability. Unauthenticated remote attackers can execute arbitrary JavaScript code in the user's browser through phishing attacks.
