Summary
Vulnerabilities in Open Source Python affect IBM Tivoli Application Dependency Discovery Manager.
Vulnerability Details
CVEID: CVE-2019-9948
DESCRIPTION: Python could allow a remote attacker to bypass security restrictions, caused by improper input validation by the urllib. By sending a specially-crafted request, an attacker could exploit this vulnerability to bypass the blocklist file: URIs protection mechanisms.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/158831 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID: CVE-2019-9947
DESCRIPTION: Python is vulnerable to HTTP header injection, caused by improper validation of input in urllib and urllib2. By persuading a victim to visit a specially-crafted Web page, a remote attacker could exploit this vulnerability to inject arbitrary HTTP headers, which will allow the attacker to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning or session hijacking.
CVSS Base score: 6.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/158830 for the current score.
