CVE-2017-14198

The Joomla UP plugin extension (lomart.fr) in versions 5.0.0-5.2.0 and 6.0.0-6.0.29 contains an unauthenticated remote code installation vulnerability. An attacker without authentication can cause malicious code to be installed in the application.

The Joomla UP plugin extension (lomart.fr) in versions 5.0.0-5.2.0 and 6.0.0-6.0.29 contains various path traversal and file access vectors. An attacker can access files outside the intended directory.

The Joomla UP plugin extension (lomart.fr) in versions 5.0.0-5.2.0 and 6.0.0-6.0.29 contains an authenticated, privileged PHP command injection vulnerability. An attacker with appropriate privileges can execute arbitrary PHP commands.

The Joomla AcyMailing Enterprise extension in versions below 11.1.0 contains a remote code execution vulnerability in the mailbox action feature. MIME parts of incoming emails were saved to media/com_acym/upload/ with no extension check, so anyone who could email the monitored mailbox could write a PHP file into the web root.

The Joomla YouTube Gallery extension (joomlaboat.com) in versions below 5.7.3 contains an unauthenticated SQL injection vulnerability in the video search and sorting functionality. An attacker can inject SQL commands into read queries.

Froxlor in versions 2.3.10 and earlier contains an incomplete fix for GHSA-c3p2 — Validate::validateUrl rejects CR/LF characters only in the path, query, and fragment components and never inspects the userinfo (user:pass@) components. An authenticated low-privilege customer with subdomain-create rights can supply a subdomain redirect URL carrying a CR/LF payload in the userinfo portion, which passes validation and is written verbatim into the generated nginx or Apache vhost configuration. Froxlor regenerates and reloads the web-server configuration as root, so injected directives take effect server-wide.

Froxlor in versions 2.3.10 and earlier contains an incomplete fix for GHSA-75h4-... — the customer data-export (DataDump) cron fails to validate intermediate path components of the export destination. Froxlor\FileDir::makeCorrectDir() contains an off-by-one in its path-component walk that skips the first segment below the customer home directory, and the guard in ExportCron.php checks only the final component with is_link(). An authenticated customer with the export feature enabled can schedule an export into a genuine subdirectory of their own webspace, then replace an intermediate path component with a symlink before the root-owned cron runs. The cron's 'chown -R' then recursively changes ownership of the linked directory tree (e.g. /etc) to the customer's UID, yielding host root and cross-tenant compromise.

Froxlor through 2.3.10 is vulnerable to arbitrary file deletion via symlink following in the FTP data deletion cron task. Cron task 8 (deleteFtpData), queued when an FTP account is deleted, calls FileDir::makeCorrectDir() without the $fixed_homedir argument, so the symlink component walk is skipped, and then executes 'rm -rf' as root on the resulting path with string-level guards only. Because makeCorrectDir() appends a trailing slash, GNU rm dereferences a symlink used either as an intermediate or final path component. An authenticated customer who can write to the FTP home directory can plant a symlink between task insertion and cron execution, causing the root cron job to recursively delete arbitrary directory trees.

Froxlor before 2.3.12 does not restrict or escape the system.letsencryptchallengepath setting — unlike sibling settings hardened in GHSA-33mp, the field has no string_regexp or required_otp guard, and its value is concatenated unescaped into the acme.sh command line built in lib/Froxlor/Cron/Http/LetsEncrypt/AcmeSh.php and executed by the root cron via FileDir::safe_exec. Because safe_exec only blacklists shell metacharacters such as ; | & > < \ $ ~ ?, spaces and quotes survive and the value is word-split into additional acme.sh arguments. An administrator, or any actor able to write settings (e.g. through the settings-import API), can inject acme.sh options such as --renew-hook, --pre-hook or --post-hook to obtain arbitrary command execution as root at the next Let's Encrypt cron run, or use --config-home/--cert-home for arbitrary file writes.

Kyverno before 1.19.1 fails to properly validate URL-encoded path segments in Policy apiCall urlPath, allowing namespace tenants to bypass the per-namespace clamp and create objects in other namespaces as the admission-controller ServiceAccount. Attackers can exploit this by using percent-encoded directory traversal sequences to create MutatingWebhookConfiguration objects cluster-wide or PolicyException objects in the kyverno namespace, enabling privilege escalation to cluster admin.
