CVE-2023-36049
Description
A vulnerability was found in FormatFtpCommand in the .NET package that may result in a CRLF injection arbitrary file write and deletion.
Statement
The vulnerability identified in FormatFtpCommand within the .NET package presents a moderate severity concern rather than an important one due to several mitigating factors. Firstly, while it allows for CRLF (Carriage Return Line Feed) injection, enabling potential arbitrary file write and deletion, its impact is limited by the context in which it can be exploited. The injection occurs within the FTP command formatting process, requiring an attacker to have authenticated access to the FTP server, thereby narrowing the pool of potential exploiters. Furthermore, successful exploitation relies on the specific implementation of the FTP server, as not all configurations may be susceptible to the arbitrary file manipulation.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
