What is CVE-2025-1451?
CVE-2025-1451 is a high-severity denial of service vulnerability in parisneo/lollms-webui, published on 20 Mar 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
A vulnerability in parisneo/lollms-webui v13 arises from the server's handling of multipart boundaries in file uploads. The server does not limit or validate the length of the boundary or the characters appended to it, allowing an attacker to craft requests with excessively long boundaries, leading to resource exhaustion and eventual denial of service (DoS). Despite an attempted patch in commit 483431bb, which blocked hyphen characters from being appended to the multipart boundary, the fix is insufficient. The server remains vulnerable if other characters (e.g., '4', 'a') are used instead of hyphens. This allows attackers to exploit the vulnerability using different characters, causing resource exhaustion and service unavailability.
Weakness: CWE-770
