CVE-2024-21544: Improper Input Validation in spatie/browsershot
Versions of the package spatie/browsershot before 5.0.1 are vulnerable to Improper Input Validation due to improper URL validation in the setUrl method. An attacker can exploit this vulnerability by using leading whitespace (%20) before the file:// protocol, resulting in Local File Inclusion, which allows the attacker to read sensitive files on the server.
AI Analysis
Technical Summary
The vulnerability in spatie/browsershot (CVE-2024-21544) arises from improper URL validation in the setUrl method. Versions prior to 5.0.1 do not correctly handle leading whitespace characters before the file:// protocol, enabling an attacker to trigger Local File Inclusion (LFI). This LFI can be exploited to read sensitive server files, potentially exposing confidential information. The CVSS 4.0 score is 7.7 (high severity), reflecting network attack vector, no privileges or user interaction required, and high scope impact.
Potential Impact
Successful exploitation allows an unauthenticated attacker to read arbitrary files on the server by bypassing URL validation, potentially exposing sensitive data. This can compromise confidentiality but does not require privileges or user interaction.
Mitigation Recommendations
Upgrade to spatie/browsershot version 5.0.1 or later, where this improper input validation vulnerability is fixed. No other mitigations are indicated. Patch status is confirmed by the version boundary (<5.0.1) and the advisory.
