An issue was discovered in TCPDF before 6.2.22. Attackers can trigger deserialization of arbitrary data via the phar:// wrapper.

LimeSurvey has a SQL Injection issue

LimeSurvey constructs account password-reset links from the client-supplied HTTP Host header without validating it.

Vulnerability in LimeSurvey 6.13.0 in the endpoint /optin that causes infinite HTTP redirects when accessed directly. This behavior can be exploited to generate a Denegation of Service (DoS attack), by exhausting server or client resources. The system is unable to break the redirect loop, which can cause service degradation or browser instability.

In version 6.13.0 of LimeSurvey, any external user can cause a 500 error in the survey system by sending a malformed session cookie. Instead of displaying a generic error message, the system exposes internal backend information, including the use of the Yii framework, the MySQL/MariaDB database engine, the table name 'limesessions', primary keys, and fragments of the content that caused the conflict. This information can simplify the collection of data about the internal architecture of the application by an attacker.

Vulnerability in LimeSurvey 6.13.0 in the endpoint /optout that causes infinite HTTP redirects when accessed directly. This behavior can be exploited to generate a Denegation of Service (DoS attack), by exhausting server or client resources. The system is unable to break the redirect loop, which can cause service degradation or browser instability.

LimeSurvey through 6.17.10 and 7.0.4 contains a server-side request forgery vulnerability in the REST API survey template endpoint that allows authenticated users to cause the server to issue arbitrary HTTP requests by supplying a manipulated Host header. Attackers can exploit the unsanitized use of the HTTP Host header in the getTemplateData() function to reach internal network services, cloud metadata endpoints, and extract sensitive credentials such as IAM tokens from instance metadata services.

Cross-site scripting (XSS) vulnerability in /application/controller/admin/theme.php in LimeSurvey 3.6.2+180406 allows remote attackers to inject arbitrary web script or HTML via the changescp parameter to the index.php/admin/themes/sa/templatesavechanges URI.

LimeSurvey is vulnerable to SQL injection

A deserialization vulnerability in LimeSurvey before v6.15.0+250623 allows a remote attacker to execute arbitrary code on the server.

Cross Site Scripting vulnerability in LimeSurvey before 6.5.0+240319 allows a remote attacker to execute arbitrary code via a lack of input validation and output encoding in the Alert Widget's message component.

Cross Site Scripting vulnerability in LimeSurvey before 6.5.12+240611 allows a remote attacker to execute arbitrary code via a crafted script to the title and comment fields.

LimeSurvey 4.3.10 contains a stored cross-site scripting vulnerability in the Survey Menu functionality of the administration panel. Attackers can inject malicious SVG scripts through the Surveymenu[title] and Surveymenu[parentid] parameters to execute arbitrary JavaScript in administrative contexts.

A flaw has been found in LimeSurvey 6.5.14-240624. Affected by this issue is the function actionUpdateSurveyLocaleSettingsGeneralSettings of the file /index.php?r=admin/database/index/updatesurveylocalesettingsgeneralsettings of the component Survey General Settings Handler. This manipulation of the argument Language causes sql injection. The attack is possible to be carried out remotely. The exploit has been published and may be used. Upgrading to version 6.6.2+240827 can resolve this issue. Patch name: d656d2c7980b7642560977f4780e64533a68e13d. You should upgrade the affected component.

LimeSurvey before v5.0.4 was discovered to contain a SQL injection vulnerability via the component /application/views/themeOptions/update.php.

Cross-site Scripting in Limesurvey

Cross-site Scripting in LimeSurvey

Cross-site Scripting in LimeSurvey

LimeSurvey 2.6.x before 2.6.7, 2.7x.x before 2.73.1, and 3.x before 3.4.2 mishandles application/controller/InstallerController.php after installation, which allows remote attackers to access the configuration file.

A Reflected Cross-Site Scripting (XSS) affects LimeSurvey versions prior to 6.15.11+250909, due to the lack of validation of gid parameter in getInstance() function in application/models/QuestionCreate.php. This allows an attacker to craft a malicious URL and compromise the logged in user.

Cross Site Scripting vulnerability in Limesurvey v.6.15.20+251021 allows a remote attacker to execute arbitrary code via the Box[title] and box[url] parameters.

SQL Injection vulnerability in Limesurvey v2.65.1+170522. This vulnerability allows an attacker to retrieve, create, update and delete database via 'token' parameter in '/index.php' endpoint.

CRLF Injection vulnerability in Limesurvey v2.65.1+170522.  This vulnerability could allow a remote attacker to inject arbitrary HTTP headers and perform HTTP response splitting attacks via '/index.php/survey/index/sid/<SID>/token/fwyfw%0d%0aCookie:%20POC'.

Cross Site Scripting (XSS) vulnerability in Lime Survey Community Edition Version v.5.3.32+220817, allows remote attackers to execute arbitrary code via the Administrator email address parameter in the General Setting function.

Lime Survey <= 6.5.12 is vulnerable to Cross Site Request Forgery (CSRF). The YIICSRFTOKEN is only checked when passed in the body of POST requests, but the same check isn't performed in the equivalent GET requests.

A vulnerability was found in LimeSurvey 6.3.0-231016 and classified as problematic. Affected by this issue is some unknown functionality of the file /index.php of the component File Upload. The manipulation of the argument size leads to denial of service. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

An unauthenticated file download vulnerability exists in LimeSurvey versions from 2.0+ up to and including 2.06+ Build 151014. The application fails to validate serialized input to the admin backup endpoint (index.php/admin/update/sa/backup), allowing attackers to specify arbitrary file paths using a crafted datasupdateinfo payload. The files are packaged in a ZIP archive and made available for download without authentication. This vulnerability can be exploited to read arbitrary files on the host system, including sensitive OS and configuration files.

A Remote Code Execution (RCE) vulnerabilty exists in LimeSurvey 5.2.4 via the upload and install plugins function, which could let a remote malicious user upload an arbitrary PHP code file.

The downloadZip function in application/controllers/admin/export.php in LimeSurvey through 3.16.1+190225 allows a relative path.

Incomplete blacklist vulnerability in the autoEscape function in commonhelper.php in LimeSurvey 2.05+ Build 140618 allows remote attackers to conduct cross-site scripting (XSS) attacks via the GBK charset in the loadname parameter to index.php, related to the survey resume.
