TitelWavlink WN530HG4B M30HG4B_V260724 Heap-based Buffer Overflow
BeschreibungThis vulnerability is a pre-auth RCE vulnerability found in the latest firmware (M30HG4B_V260724) of WAVLINK's WN530HG4B product. It is triggered by manipulating heap chunk metadata through a heap overflow. An attacker can supply input to api.cgi, and because the code copies user-supplied untrusted input without checking its length, the vulnerability occurs. The RCE vulnerability was successfully exploited using single binary emulation with QEMU. For further details, please refer to the advisory/exploit link below. Here is the link to download the lastest firmware of WN530HG4B: https://docs.wavlink.xyz/Firmware/?category=Router&model=WL-WN530HG4B
