Descriptions

In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename.

En las versiones 2.4.0 hasta la 2.4.29 de Apache httpd, la expresión especificada en podría unir "$" con un carácter nueva línea o newline en un nombre de archivo malicioso, en lugar de interpretarse, únicamente, como el final del nombre de archivo. Esto se podría explotar en entornos donde las subidas de algunos archivos están bloqueadas de manera externa, pero solo uniendo la porción final del nombre del archivo.
