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.

Emlog is an open source website building system. Emlog Pro versions pro-2.5.7 and pro-2.5.8 contain an SQL injection vulnerability. searchcontroller.php does not use addslashes after urldecode, allowing the preceeding addslashes to be bypassed by URL double encoding. This could result in potential leakage of sensitive information from the user database. Version pro-2.5.9 fixes the issue.

Emlog is an open source website building system. Versions 2.5.13 and prior have a deserialization vulnerability. A user who creates a carefully crafted nickname can cause strreplace to replace the value of nameorig with empty, causing deserialization to fail and return false. Commit 9643250802188b791419e3c2188577073256a8a2 fixes the issue.

Emlog is an open source website building system. Emlog Pro prior to version 2.5.10 contains a file upload vulnerability. The store.php component contains a critical security flaw where it fails to properly validate the contents of remotely downloaded ZIP plugin files. This insufficient validation allows attackers to execute arbitrary code on the vulnerable system. Version 2.5.10 contains a patch for the issue.

A vulnerability has been found in Emlog Pro 2.5.11 and classified as critical. This vulnerability affects unknown code of the file /include/controller/apicontroller.php. The manipulation of the argument tag leads to sql injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure and confirmed the existence of the vulnerability.

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 Reason: This candidate was withdrawn by its CNA.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.

Deserialization of Untrusted Data in emlog pro v.2.1.15 and earlier allows a remote attacker to execute arbitrary code via the cache.php component.

An arbitrary file upload vulnerability in the component /content/templates/ of Emlog Pro v2.2.0 allows attackers to execute arbitrary code via uploading a crafted PHP file.

An arbitrary file upload vulnerability in the component /admin/plugin.php of Emlog Pro v2.2.0 allows attackers to execute arbitrary code via uploading a crafted PHP file.

A Remote Code Execution (RCE) vulnerability exists in emlog 5.3.1 via content/plugins.

Vulnerability in emlog v6.0.0 allows user to upload webshells via zip plugin module.

emlog through 6.0.0beta has an arbitrary file deletion vulnerability via an admin/data.php?action=dellallbak request with directory traversal sequences in the bak[] parameter.

Emlog v6.0 was discovered to contain a SQL injection vulnerability via the $TagID parameter of getblogidsfromtagid().

emlog v5.3.1 and emlog v6.0.0 have a Remote Code Execution vulnerability due to upload of database backup file in admin/data.php.

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 is an open source website building system. In version 2.5.23, Emlog Pro is vulnerable to a session verification code error due to a clearing logic error. This means the verification code could be reused anywhere an email verification code is required. This issue has been fixed in commit 1f726df.

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. In versions up to and including 2.5.9, SQL injection occurs because the $origContent parameter in admin/articlesave.php is not strictly filtered. Since admin/articlesave.php can be accessed by ordinary registered users, this will cause SQL injection to occur when the registered site is enabled, resulting in the injection of the admin account and password, which is then exploited by the backend remote code execution. As of time of publication, it is unknown whether a fix exists.

Emlog is an open source website building system. Emlog Pro versions 2.5.19 and earlier are vulnerable to Cross‑Site Request Forgery (CSRF) on the password change endpoint. An attacker can trick a logged‑in administrator into submitting a crafted POST request to change the admin password without consent. Impact is account takeover of privileged users. Severity: High. As of time of publication, no known patched versions exist.

emlog v6.0.0 has CSRF via the admin/user.php?action=new URI.

An issue was discovered in emlog 6.0.0stable. There is a SQL Injection vulnerability that can execute any SQL statement and query server sensitive data via admin/navbar.php?action=addpage.

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. A cross-site scripting (XSS) vulnerability in emlog up to and including pro-2.5.17 allows remote attackers to inject arbitrary web script or HTML via the keyword parameter. Due to lack of sanitization it is possible to inject HTML/JS code into keyword parameter. If one persuades an user into clicking into prepared link it is possible to execute any JS code in admin's browser. As of time of publication, no known patched versions exist.

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.
