Configuration tampering via unneutralized CRLF sequences
Published Apr 20, 2026 · Updated Apr 20, 2026
CRLF injection in Silex SD-330AC 1.42 and earlier and AMC Manager 5.0.2 and earlier allows remote attackers to alter system configuration. The configuration-processing path accepts carriage-return and line-feed characters in crafted configuration data and writes the resulting extra lines as arbitrary entries in the system configuration file. The attack requires unauthenticated access from the same local network, and injected entries can change settings or interrupt service; Silex has not disclosed the exact field or parser.
