The OpenTelemetry Collector module AWS firehose receiver is for ingesting AWS Kinesis Data Firehose delivery stream messages and parsing the records received based on the configured record type. `awsfirehosereceiver` allows unauthenticated remote requests, even when configured to require a key. OpenTelemetry Collector can be configured to receive CloudWatch metrics via an AWS Firehose Stream. Firehose sets the header `X-Amz-Firehose-Access-Key` with an arbitrary configured string. The OpenTelemetry Collector awsfirehosereceiver can optionally be configured to require this key on incoming requests. However, when this is configured it **still accepts incoming requests with no key**. Only OpenTelemetry Collector users configured with the “alpha” `awsfirehosereceiver` module are affected. This module was added in version v0.49.0 of the “Contrib” distribution (or may be included in custom builds). There is a risk of unauthorized users writing metrics. Carefully crafted metrics could hide other malicious activity. There is no risk of exfiltrating data. It’s likely these endpoints will be exposed to the public internet, as Firehose does not support private HTTP endpoints. A fix was introduced in PR #34847 and released with v0.108.0. All users are advised to upgrade. There are no known workarounds for this vulnerability.

PHPSpreadsheet is a pure PHP library for reading and writing spreadsheet files. Affected versions are subject to a bypassing of a filter which allows for an XXE-attack. This in turn allows attacker to obtain contents of local files, even if error reporting is muted. This vulnerability has been addressed in release version 2.2.1. All users are advised to upgrade. There are no known workarounds for this vulnerability.

PHPSpreadsheet is a pure PHP library for reading and writing spreadsheet files. In affected versions `\PhpOffice\PhpSpreadsheet\Writer\Html` doesn't sanitize spreadsheet styling information such as font names, allowing an attacker to inject arbitrary JavaScript on the page. As a result an attacker may used a crafted spreadsheet to fully takeover a session of a user viewing spreadsheet files as HTML. This issue has been addressed in release version 2.1.0. All users are advised to upgrade. There are no known workarounds for this vulnerability.

i-Educar is free, completely online school management software that allows school secretaries, teachers, coordinators and area managers. In affected versions Creating a SQL query from a concatenation of a user-controlled GET parameter allows an attacker to manipulate the query. Successful exploitation of this flaw allows an attacker to have complete and unrestricted access to the database, with a web user with minimal permissions. This may involve obtaining user information, such as emails, password hashes, etc. This issue has not yet been patched. Users are advised to contact the developer and to coordinate an update schedule.

i-Educar is free, completely online school management software that allows school secretaries, teachers, coordinators and area managers. An attacker with only minimal viewing privileges in the settings section is able to change their user type to Administrator (or another type with super-permissions). Any user is capable of becoming an administrator, which can lead to account theft, changing administrative tasks, etc. The failure occurs in the file located in ieducar/intranet/educar_usuario_cad.php on line 446 , which does not perform checks on the user's current permission level to make changes. This issue has not yet been patched. Users are advised to contact the developer and to coordinate an update schedule.

i-Educar is free, completely online school management software that allows school secretaries, teachers, coordinators and area managers. The lack of sanitization of user-controlled parameters for generating HTML field values ​​dynamically leads to XSS (Cross-Site Scripting) attacks. The dynamic generation of HTML fields in the ieducar/intranet/include/clsCampos.inc.php file does not perform the correct validation or sanitization, reflecting the user-controlled values ​​to be shown in the page's HTML. This allows an attacker to inject a specific XSS payload into a parameter. Successful exploitation of this flaw allows an attacker to trick the victim into clicking a vulnerable URL, enabling JavaScript scripts to be executed in the browser. Due to the configuration of session cookies, with the HttpOnly and SameSite=Lax flags being defined, there is little an attacker can do to steal the session or force the victim to perform actions within the application. This issue hast been patched but a new release has not yet been made. Users are advised to contact the developer and to coordinate an update schedule.
