Emlog is an open source website building system. Prior to version 2.6.11, direct SQL injection in article creation and update functions allows attackers to execute arbitrary SQL commands, potentially leading to complete database compromise, data theft, or system destruction. This issue has been patched in version 2.6.11.

An arbitrary file upload vulnerability in the component admin\plugin.php of Emlog Pro v2.5.3 allows attackers to execute arbitrary code via uploading a crafted Zip file.

An arbitrary file upload vulnerability in the component /views/plugin.php of emlog pro v2.5.7 allows attackers to execute arbitrary code via uploading a crafted PHP file.

Rejected reason: REJECT DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by its CNA. Further investigation showed that it was not a security issue. Notes: The file upload in include/service/media.php verifies the file extension based on a list defined in include/lib/option.php. This whitelist prevents unrestricted uploads (e.g. PHP files). Therefore, the attack possibility is just of theoretical nature.

A security vulnerability has been detected in Emlog Pro up to 2.5.18. This affects an unknown function of the file /admin/blogger.php?action=updateavatar. Such manipulation of the argument image leads to unrestricted upload. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Emlog is an open source website building system. In version 2.5.23, article creation functionality is vulnerable to cross-site request forgery (CSRF). This can lead to a user being forced to post an article with arbitrary, attacker-controlled content. This, when combined with stored cross-site scripting, leads to account takeover. As of time of publication, no known patched versions are available.

Emlog is an open source website building system. emlog v2.6.1 and earlier exposes a REST API endpoint (/index.php?rest-api=upload) for media file uploads. The endpoint fails to implement proper validation of file types, extensions, and content, allowing authenticated attackers (with a valid API key or admin session cookie) to upload arbitrary files (including malicious PHP scripts) to the server. An attacker can obtain the API key either by gaining administrator access to enable the REST API setting, or via information disclosure vulnerabilities in the application. Once uploaded, the malicious PHP file can be executed to gain remote code execution (RCE) on the target server, leading to full server compromise.

Emlog Pro 2.5.20 has an arbitrary file deletion vulnerability. This vulnerability stems from the admin/template.php component and the admin/plugin.php component. They fail to perform path verification and dangerous code filtering for deletion parameters, allowing attackers to exploit this feature for directory traversal.

Emlog is an open source website building system. Prior to version 2.6.8, the backend upgrade interface accepts remote SQL and ZIP URLs via GET parameters. The server first downloads and executes the SQL file, then downloads the ZIP file and extracts it directly into the web root directory. This process does not validate a CSRF token. Therefore, an attacker only needs to trick an authenticated administrator into visiting a malicious link to achieve arbitrary SQL execution and arbitrary file write. This issue has been patched in version 2.6.8.

Emlog is an open source website building system. In 2.6.13 and earlier, the admin backend user search module's keyword parameter from admin/user.php is processed with addslashes but not HTML-escaped before being rendered into the value attribute in admin/views/user.php, allowing reflected cross-site scripting in an administrator's backend session. No fixed version is currently identified.

Emlog is an open source website building system. Prior to version 2.6.11, missing CSRF protection in critical admin functions allows attackers to trick authenticated administrators into performing unauthorized actions like system registration, plugin management, and configuration changes. This issue has been patched in version 2.6.11.

Emlog is an open source website building system. Versions up to and including 2.5.19 are vulnerable to server-side Out-of-Band (OOB) requests / SSRF via uploaded SVG files. An attacker can upload a crafted SVG to http[:]//emblog/admin/media[.]php which contains external resource references. When the server processes/renders the SVG (thumbnailing, preview, or sanitization), it issues an HTTP request to the attacker-controlled host. Impact: server-side SSRF/OOB leading to internal network probing and potential metadata/credential exposure. As of time of publication, no known patched versions are available.

A cross-site scripting (XSS) vulnerability in Emlog Pro v2.5.4 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the article header at /admin/article.php.

Emlog is an open source website building system. In 2.6.6 and earlier, the deleteasync action (asynchronous delete) lacks a call to LoginAuth::checkToken(), enabling CSRF attacks.

Emlog Pro V2.5.7 is vulnerable to Unrestricted Upload of File with Dangerous Type via /emlog/admin/plugin.php?action=uploadzip

Emlog is an open source website building system. In versions 2.6.2 and prior, a path traversal vulnerability exists in the emUnZip() function (include/lib/common.php:793). When extracting ZIP archives (plugin/template uploads, backup imports), the function calls $zip->extractTo($path) without sanitizing ZIP entry names. An authenticated admin can upload a crafted ZIP containing entries with ../ sequences to write arbitrary files to the server filesystem, including PHP webshells, achieving Remote Code Execution (RCE). At time of publication, there are no publicly available patches.

The template upload feature in Emlog Pro v2.6.9 has a path traversal vulnerability, allowing authenticated administrators to execute arbitrary PHP code. By uploading a malicious ZIP archive containing directory traversal sequences in filenames, an attacker can overwrite default template files or directly include malicious code files in the current template.

Emlog Pro 1.6.0 plugins upload suffers from a remote code execution (RCE) vulnerability.

A cross-site scripting (XSS) vulnerability in Emlog Pro v2.5.4 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the Titile in the article category section.

A Server-Side Request Forgery (SSRF) in the component sort.php of Emlog Pro v2.5.4 allows attackers to scan local and internal ports via supplying a crafted URL.

Emlog is an open source website building system. Version 2.5.23 has a stored cross-site scripting vulnerability that can lead to account takeover, including takeover of admin accounts. As of time of publication, no known patched versions are available.

Emlog is an open source website building system. In 2.6.26 and earlier, missing CSRF protection on the AI Assistant executetool action in admin/ai.php lets a remote unauthenticated attacker submit a forged cross-site request from an attacker-controlled page to a recently logged-in administrator. The authentication cookie set in include/lib/loginauth.php has no explicit SameSite attribute, enabling Chrome's temporary Lax+POST grace window. The querydatabase case passes attacker-controlled sql and confirmcode values to Ai::queryDatabase in include/service/ai.php; read queries need no confirmation, write queries accept the public confirm string, only the blog table is write-protected, and aliasing password as pwdhash bypasses output redaction. A successful request can read every database table and write every table except blog, including changing the user table to take over an administrator account. No fixed version is available as of this review.

Emlog is an open source website building system. In versions 2.6.2 and prior, a Local File Inclusion (LFI) vulnerability exists in admin/plugin.php at line 80. The $plugin parameter from the GET request is directly used in a requireonce path without proper sanitization. If the CSRF token check can be bypassed (see potential bypass conditions), an attacker can include arbitrary PHP files from the server filesystem, leading to code execution. At time of publication, there are no publicly available patches.

Emlog is an open source website building system. In versions 2.6.2 and prior, a SQL injection vulnerability exists in include/model/tagmodel.php at line 168. The updateTagName() function directly interpolates user input into the SQL query string without using parameterized queries or proper escaping ($this->db->escapestring()), making it vulnerable to SQL injection attacks. At time of publication, there are no publicly available patches.

A vulnerability was found in Emlog Pro 2.3.4. It has been classified as problematic. This affects an unknown part of the component Cookie Handler. The manipulation of the argument AuthCookie leads to improper authentication. It is possible to initiate the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. The identifier VDB-264741 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
