Description
This security bulletin contains information about 5 vulnerabilities.
1) Input validation error (CVE-ID: CVE-2024-35176)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when parsing XML that has multiple bracket character occurrences (e.g. "<") in an attribute value. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
2) Input validation error (CVE-ID: CVE-2024-39908)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied XML input. A remote attacker can pass specially crafted characters, such as "<", "\0" and "%>" to the application and perform a denial of service (DoS) attack.
3) Input validation error (CVE-ID: CVE-2024-41123)
CWE-ID: CWE-20 - Improper input validation
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:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when parsing characters such as a whitespace character, >] and ]>. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
4) XML Entity Expansion (CVE-ID: CVE-2024-41946)
CWE-ID: CWE-776 - Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion')
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:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation when parsing XML with SAX2 or pull parser API. A remote attacker can pass specially crafted XML data to the application and perform a denial of service attack.
5) Inefficient regular expression complexity (CVE-ID: CVE-2024-49761)
CWE-ID: CWE-1333 - Inefficient Regular Expression Complexity
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation when parsing an XML that has many digits between &# and x...; in a hex numeric character reference (&#x...;). A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
