A vulnerability in the web-based management interface of Cisco Small Business RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers could allow an authenticated, remote attacker to elevate privileges on an affected device. This vulnerability exists because the web-based management interface discloses sensitive information. An attacker could exploit this vulnerability by sending crafted HTTP input to an affected device. A successful exploit could allow an attacker to elevate privileges from guest to admin.

Detection & IOCsextracted from sources · hover to see the quote

  • Vulnerability is exploitable via crafted HTTP input to the web-based management interface; monitor for anomalous or unexpected HTTP requests to the RV340/RV340W/RV345/RV345P management interface, particularly those that result in privilege changes from guest to admin.
  • The vulnerability stems from sensitive information disclosure in the web-based management interface; audit responses from the management interface for unintended exposure of credentials or session tokens that could be leveraged for privilege escalation.
  • Track Cisco bug IDs CSCwk99655 and CSCwm27935 for any future threat intelligence or PoC disclosures related to this CVE.
  • ·Cisco PSIRT will continue disclosing vulnerabilities for these products until their Last Dates of Support, meaning additional CVEs for the same device family may follow.
