New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 4.5
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201001-09 (Ruby: Terminal Control Character Injection)
Giovanni Pellerano, Alessandro Tanasi and Francesco Ongaro reported that WEBrick does not filter terminal control characters, for instance when handling HTTP logs.
A remote attacker could send a specially crafted HTTP request to a WEBrick server to inject arbitrary terminal control characters, possibly resulting in the execution of arbitrary commands, data loss, or other unspecified impact. This could also be used to facilitate other attacks.
There is no known workaround at this time.
