parisneo/lollms-webui: Improper Control of Filename for Include/Require Statement in PHP Program

Published Updated By the CyberSecBulletin desk

CVE-2024-1600 is a critical-severity improper control of filename for include/require statement in PHP program vulnerability in parisneo/lollms-webui from ParisNeo, with a CVSS 3.0 base score of 9.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 9.5 as the first without the flaw, so updating parisneo/lollms-webui to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 32.5% chance of exploitation within 30 days, which is in the top 1.64% of all scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update parisneo/lollms-webui to 9.5 or a later version.
  2. Update lollms-webui to 9.5 or a later version.
  3. Update Lollms Web UI to 9.6 or a later version.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

A Local File Inclusion (LFI) vulnerability exists in the parisneo/lollms-webui application, specifically within the `/personalities` route. An attacker can exploit this vulnerability by crafting a URL that includes directory traversal sequences (`../../`) followed by the desired system file path, URL encoded. Successful exploitation allows the attacker to read any file on the filesystem accessible by the web server. This issue arises due to improper control of filename for include/require statement in the application.

The underlying weakness: Improper Control of Filename for Include/Require Statement in PHP Program

The PHP application receives input from an upstream component, but it does not restrict or incorrectly restricts the input before its usage in require, include, or similar functions.

How developers prevent this class of flaw

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs. For example, ID 1 could map to inbox.txt and ID 2 could map to profile.txt. Features such as the ESAPI AccessReferenceMap provide this capability.
  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
