Description
This security bulletin contains information about 7 vulnerabilities.
1) Cross-site scripting (CVE-ID: CVE-2015-9251)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear
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 when a cross-domain Ajax request is performed without the dataType option. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary text/javascript responses 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) Prototype pollution (CVE-ID: CVE-2019-11358)
CWE-ID: CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes (\'Prototype Pollution\')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to execute arbitrary JavaScript code.
The vulnerability exists due to improper input validation. A remote attacker can pass specially crafted input to the application and perform prototype pollution, which can result in information disclosure or data manipulation.
3) Cross-site scripting (CVE-ID: CVE-2020-11022)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:P/U:Clear
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 regex operation in "jQuery.htmlPrefilter". A remote attacker can pass specially crafted data to the application that uses .html()</code>, <code>.append() or similar methods for it and execute arbitrary JavaScript 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.
4) Cross-site scripting (CVE-ID: CVE-2020-11023)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:A/U:Clear
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 when passing <option> elements to jQuery’s DOM manipulation methods. A remote attacker can execute arbitrary JavaScript 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.
5) Inadequate Encryption Strength (CVE-ID: CVE-2005-4900)
CWE-ID: CWE-326 - Inadequate Encryption Strength
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to inadequate encryption strength. A remote attacker can decrypt the data using spoofing attacks.
6) Sensitive Cookie Without 'HttpOnly' Flag (CVE-ID: CVE-2023-4217)
CWE-ID: CWE-1004 - Sensitive Cookie Without 'HttpOnly' Flag
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
