CVE-2013-4659: Buffer overflow in Broadcom ACSD allows remote attackers to execute arbitrary code via a long string to TCP...

Security readout for executives and security teams

CVE-2013-4659 is a router vulnerability in Broadcom ACSD. A remote attacker who can reach TCP port 5916 could trigger a buffer overflow with overly long input and potentially run code on the device. The record cites multiple vendors’ routers, including ASUS RT-AC66U and TRENDnet TEW-812DRU. Exposure is most likely on SOHO or small-office routers using Broadcom ACSD where TCP port 5916 is reachable from untrusted networks. The source data names ASUS RT-AC66U and TRENDnet TEW-812DRU but does not provide a complete affected-product list. Treat this as urgent for internet-facing or unmanaged routers. The business risk is device takeover at the network edge, but prioritization should focus on confirmed affected models because the public CVE record lacks full version and patch detail. Mitigation focus: Check vendor firmware advisories for affected router models and apply supported updates.; Block TCP port 5916 from the internet and other untrusted networks.; Disable unnecessary management or auxiliary router services where vendor guidance permits..
