What to do

No fixed build or workaround is published yet. Limit exposure and watch for a patch.

Steps

Written by AI from the record

Check whether your Joomla site has Picture Calendar version 3.1.4 installed and whether its list.php page is reachable online.
No vendor-fixed version has been published; contact the component vendor or maintainer for a supported replacement or security update.
Until it is removed or replaced, restrict public access to the Picture Calendar component, especially list.php.
Review web-server access logs for unusual requests to list.php containing folder paths or repeated ../ sequences.

What it is

From the CVE record

Directory Traversal exists in the Picture Calendar 3.1.4 component for Joomla! via the list.php folder parameter.

In plain language

Written by AI from the record

Picture Calendar 3.1.4 can let an internet-based attacker read files on your web server, so small businesses using it should act promptly.

Unauthenticated directory traversal in Picture Calendar 3.1.4 list.php permits arbitrary readable-file disclosure through manipulation of the folder parameter.

If you're affected

Web-server file exposure
Password file disclosure
Configuration data exposure
Privacy breach risk

What is it

This is a flaw in a website calendar add-on that can let a visitor ask the server for files outside the calendar’s own folder. It is like a filing cabinet clerk accepting a request for one drawer but then being tricked into opening other drawers in the office.

Who is affected

This matters to you if you run Picture Calendar 3.1.4 on a Joomla website. It is a risk when the component is accessible over the network; an attacker does not need an account or someone to click anything.

How urgent is it

A public exploit is available, making attempted abuse easier for attackers. This is an amber-priority issue: address it promptly, especially for an internet-facing site, but it is not listed as a known actively exploited vulnerability by the U.S. government.

What to do — in detail

Confirm installation by reviewing the Joomla extension inventory and deployed component files for Picture Calendar 3.1.4. Confirm exposure by checking whether the component’s list.php endpoint is reachable externally, then inspect access logs for traversal-style folder values such as ../.

No patched or fixed version is documented, so there is no supported target version or branch upgrade path to provide. If patching is delayed, disable or remove the component, replace it with a maintained alternative, or block external requests to its list.php endpoint at the web server or web application firewall. No CISA KEV remediation due date applies because this CVE is not in the KEV catalog. Monitor server and application logs for requests to list.php with encoded paths, ../ patterns, or unexpected folder parameters, and investigate any evidence of sensitive-file access.

Technical context

CVE-2018-6397 is CVSS 7.5 High (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), CWE-22 directory traversal. The network-reachable list.php folder parameter can be manipulated without authentication or user interaction to read arbitrary files that the web-server process can access. One public exploit is known. EPSS is 11.9% (96th percentile) and falling; this is a prediction, not confirmation of exploitation. The CVE is not listed in CISA KEV, and no patch information is available.

This is a general assessment based on public vulnerability data. It does not account for your specific infrastructure — when in doubt, consult a security specialist.
