Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, RV082, RV320, and RV325 Routers could allow an authenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly. These vulnerabilities are due to improper validation of user-supplied input in the web-based management interface. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a denial of service (DoS) condition. To exploit these vulnerabilities, an attacker would need to have valid administrator credentials on the affected device.

CVE-2021-21897 [HIGH] Vulnerability Spotlight: Heap buffer overflow vulnerability in Ribbonsoft dxflib library
## Vulnerability Spotlight: Heap buffer overflow vulnerability in Ribbonsoft dxflib library
Lilith >_> of Cisco Talos discovered this vulnerability.
Cisco Talos recently discovered an exploitable heap-based buffer overflow vulnerability in Ribbonsoft’s dxflib library that could lead to code execution.
The dxflib library is a C++ library utilized by digital design software such as QCAD and KiCad to parse DXF files for reading and writing. TALOS-2021-1346 (CVE-2021-21897) is a vulnerability that arises if an attacker were to provide the user with a specially crafted .dxf file. The attacker could cause a heap buffer overflow, which could eventually allow them to execute remote code on the victim machine.
Cisco Talos worked with Ribbonsoft to ensure that this issue is resolved and an updat
