Unrestricted file upload vulnerability in admin/code/tcefunctionstcecodeeditor.php in TCExam 10.1.006 and 10.1.007 allows remote attackers to execute arbitrary code by uploading a file with an executable extension, then accessing it via a direct request to the file in cache/.

When access to the "admin" folder is not protected by some external authorization mechanisms e.g. Apache Basic Auth, it is possible for any user to download protected information like exam answers.

Multiple XSS (CWE-79)

A reflected cross-site scripting vulnerability exists in TCExam <= 14.8.3. The paths provided in the f, d, and dir parameters in tcefilemanager.php were not properly validated and could cause reflected XSS via the unsanitized output of the path supplied. An attacker could craft a malicious link which, if triggered by an administrator, could result in the attacker hijacking the victim's session or performing actions on their behalf.

A reflected cross-site scripting vulnerability exists in TCExam <= 14.8.4. The paths provided in the f, d, and dir parameters in tceselectmediafile.php were not properly validated and could cause reflected XSS via the unsanitized output of the path supplied. An attacker could craft a malicious link which, if triggered by an administrator, could result in the attacker hijacking the victim's session or performing actions on their behalf.

Insufficient output sanitization in TCExam 14.2.2 allows a remote, unauthenticated attacker to conduct persistent cross-site scripting (XSS) attacks via the self-registration feature.

Insufficient output sanitization in TCExam 14.2.2 allows a remote, unauthenticated attacker to conduct persistent cross-site scripting (XSS) attacks via the self-registration feature.

TCExam before 14.1.2 has XSS via an ff or xl field.

Multiple SQL injection vulnerabilities in Nicola Asuni TCExam before 11.3.009 allow remote authenticated users with level 5 or greater permissions to execute arbitrary SQL commands via the (1) usergroups[] parameter to admin/code/tceedittest.php or (2) subjectid parameter to admin/code/tceshowallquestions.php.

A stored cross-site scripting vulnerability exists in TCExam <= 14.8.1. Valid files uploaded via tceselectmediafile.php with a filename beggining with a period will be rendered as text/html. An attacker with access to tceselectmediafile.php could upload a malicious javascript payload which would be triggered when another user views the file.

A stored cross-site scripting vulnerability exists in TCExam <= 14.8.1. Valid files uploaded via tcefilemanager.php with a filename beggining with a period will be rendered as text/html. An attacker with access to tcefilemanager.php could upload a malicious javascript payload which would be triggered when another user views the file.

Insufficient output sanitization in TCExam 14.2.2 allows a remote, authenticated attacker to conduct persistent cross-site scripting (XSS) attacks by creating a crafted operator.

Insufficient output sanitization in TCExam 14.2.2 allows a remote, authenticated attacker to conduct persistent cross-site scripting (XSS) attacks by creating a crafted test.

Insufficient output sanitization in TCExam 14.2.2 allows a remote, authenticated attacker to conduct persistent cross-site scripting (XSS) attacks by creating a crafted test.

Insufficient output sanitization in TCExam 14.2.2 allows a remote, authenticated attacker to conduct persistent cross-site scripting (XSS) attacks by creating a crafted group.

An exposure of sensitive information vulnerability exists in TCExam <= 14.8.1. If a password reset request was made for an email address that was not registered with a user then we would be presented with an ‘unknown email’ error. If an email is given that is registered with a user then this error will not appear. A malicious actor could abuse this to enumerate the email addresses of

TCExam 11.1.015 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by public/code/tcepagefooter.php and certain other files.

Relative Path Traversal in TCExam 14.2.2 allows a remote, authenticated attacker to read the contents of arbitrary files on disk.

A vulnerability was identified in Tecnick TCExam 16.5.0. This impacts an unknown function of the file /admin/code/tceeditgroup.php of the component Group Handler. Such manipulation of the argument Name leads to cross site scripting. The attack may be launched remotely. The exploit is publicly available and might be used. The presence of this vulnerability remains uncertain at this time. The affected component should be upgraded. The vendor explained: "I was not able to reproduce the same exploit as the TCExam version was already advanced in the meanwhile." Therefore, it can be assumed that this issue got fixed in a later release.

A security flaw has been discovered in Tecnick TCExam up to 16.6.0. Affected is the function Fxmlexportusers of the file admin/code/tcexmlusers.php of the component XML Export. Performing a manipulation results in cross site scripting. Remote exploitation of the attack is possible. There are still doubts about whether this vulnerability truly exists. Upgrading to version 16.6.1 is able to address this issue. The patch is named 899b5b2fa09edfe16043f07265e44fe2022b7f12. It is suggested to upgrade the affected component. When the vendor was informed about another security issue, he identified and fixed this flaw during analysis. He doubts the impact of this: "However, this is difficult to justify as security issue. It requires to be administrator to both create and consume the exploit. Administrators can do pretty much anything in the platform, so I don't see the point of this from a security perspective." This is reflected by the CVSS vector.

Multiple cross-site scripting (XSS) vulnerabilities in admin/code/tceselectuserspopup.php in Nicola Asuni TCExam before 11.3.009 allow remote attackers to inject arbitrary web script or HTML via the (1) cid or (2) uids parameter.

Improper Control of Resource Identifiers in TCExam 14.2.2 allows a remote, authenticated attacker to access test metadata for which they don't have permission.

Cross-site scripting (XSS) vulnerability in admin/code/tceeditanswer.php in TCExam before 11.3.008 allows remote authenticated users with level 5 or greater permissions to inject arbitrary web script or HTML via the questionsubjectid parameter.
