An issue was discovered in EspoCRM before 5.6.9. Stored XSS in the body of an Article was executed when a victim opens articles received through mail. This Article can be formed by an attacker using the Knowledge Base feature in the tab list. The attacker could inject malicious JavaScript inside the body of the article, thus helping him steal victims' cookies (hence compromising their accounts).

An issue was discovered in EspoCRM before 5.6.9. Stored XSS was executed on the Preference page as well as while sending an email when a malicious payload was inserted inside the Email Signature in the Preference page. The attacker could insert malicious JavaScript inside his email signature, which fires when the victim replies or forwards the mail, thus helping him steal victims' cookies (hence compromising their accounts).

An issue was discovered in EspoCRM before 5.6.9. Stored XSS was executed when a attacker sends an attachment to admin with malicious JavaScript in the filename. This JavaScript executed when an admin selects the particular file from the list of all attachments. The attacker could inject the JavaScript inside the filename and send it to users, thus helping him steal victims' cookies (hence compromising their accounts).

An issue was discovered in EspoCRM before 5.6.9. Stored XSS was executed inside the title and breadcrumb of a newly formed entity available to all the users. A malicious user can inject JavaScript in these values of an entity, thus stealing user cookies when someone visits the publicly accessible link.

An issue was discovered in EspoCRM before 5.6.9. Stored XSS was executed when a victim clicks on the Edit Dashboard feature present on the Homepage. An attacker can load malicious JavaScript inside the add tab list feature, which would fire when a user clicks on the Edit Dashboard button, thus helping him steal victims' cookies (hence compromising their accounts).

Dolibarr ERP/CRM 9.0.1 was affected by stored XSS within uploaded files. These vulnerabilities allowed the execution of a JavaScript payload each time any regular user or administrative user clicked on the malicious link hosted on the same domain. The vulnerabilities could be exploited by low privileged users to target administrators. The viewimage.php page did not perform any contextual output encoding and would display the content within the uploaded file with a user-requested MIME type.

Dolibarr ERP/CRM 9.0.1 provides a module named website that provides for creation of public websites with a WYSIWYG editor. It was identified that the editor also allowed inclusion of dynamic code, which can lead to code execution on the host machine. An attacker has to check a setting on the same page, which specifies the inclusion of dynamic content. Thus, a lower privileged user of the application can execute code under the context and permissions of the underlying web server.

Dolibarr ERP/CRM 9.0.1 provides a web-based functionality that backs up the database content to a dump file. However, the application performs insufficient checks on the export parameters to mysqldump, which can lead to execution of arbitrary binaries on the server. (Malicious binaries can be uploaded by abusing other functionalities of the application.)

EspoCRM 5.6.4 is vulnerable to user password hash enumeration. A malicious authenticated attacker can brute-force a user password hash by 1 symbol at a time using specially crafted api/v1/User?filterList filters.

EspoCRM 5.6.4 is vulnerable to stored XSS due to lack of filtration of user-supplied data in the Knowledge base. A malicious attacker can inject JavaScript code in the body parameter during api/v1/KnowledgeBaseArticle knowledge-base record creation.
