Description
This security bulletin contains information about 2 vulnerabilities.
1) Cross-site scripting (CVE-ID: CVE-2011-1058)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in the reStructuredText (rst) parser in parser/text_rst.py in MoinMoin before 1.9.3, when docutils is installed or when "format rst" is set,. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-4404)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote #AU# to read and manipulate data.
security/__init__.py in MoinMoin 1.9 through 1.9.4 does not properly handle group names that contain virtual group names such as "All," "Known," or "Trusted," which allows remote authenticated users with virtual group membership to be treated as a member of the group.
