Vendor not specified by the source
Description’s affected range: before 6.0.40
Component: Not specified by the source
Attack conditions (NVD, CVSS 2.0): Network (remote)
What an attacker can do
The source says integer overflow in java/org/apache/tomcat/util/buf/Ascii.java in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4, when operated behind a reverse proxy, allows remote attackers to conduct HTTP request smuggling attacks via a crafted Content-Length HTTP header. NVD’s CVSS 2.0 assessment (base score 4.3/10) rates confidentiality and availability impact as none; integrity impact as partial.
