CVE-2011-1499
Estado: ModificadaBaja (2.6)—
acl.c in Tinyproxy before 1.8.3, when an Allow configuration setting specifies a CIDR block, permits TCP connections from all IP addresses, which makes it easier for remote attackers to hide the origin of web traffic by leveraging the open HTTP proxy server.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:H/Au:N/C:N/I:P/A:N
- Puntuación base: 2.6
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.75%
