Vulnerability from variot - Updated: 2025-04-20 23:34

A vulnerability in the handling of list headers in Cisco cBR Series Converged Broadband Routers could allow an unauthenticated, remote attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Cisco cBR-8 Converged Broadband Routers running vulnerable versions of Cisco IOS XE are affected. More Information: CSCux40637. Known Affected Releases: 15.5(3)S 15.6(1)S. Known Fixed Releases: 15.5(3)S2 15.6(1)S1 15.6(2)S 15.6(2)SP 16.4(1). ( Reload device ) There are vulnerabilities that are put into a state. Vendors have confirmed this vulnerability Bug ID CSCux40637 It is released as.Remote attacker could disrupt service operation ( Reload device ) There is a possibility of being put into a state. CiscocBRSeriesConvergedBroadbandRouters is a router device. CiscocBRSeriesConvergedBroadbandRouters handles security holes in the list header field, allowing remote attackers to exploit vulnerabilities to submit special requests for denial of service attacks. Attackers can exploit this issue to cause a denial-of-service condition, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCux40637. The platform supports the application of software-defined networking (SDN) and virtualization technologies to virtualize, integrate and automate cable operators' access architectures and more

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

    Related by attack behaviour

    Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
