Description
This security bulletin contains information about 7 vulnerabilities.
1) 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.
2) 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.
3) 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.
4) Resource exhaustion (CVE-ID: CVE-2024-43398)
CWE-ID: CWE-400 - Resource exhaustion
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 application does not properly control consumption of internal resources when parsing XML with multiple deep elements that have same local name attributes. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
5) Inefficient regular expression complexity (CVE-ID: CVE-2025-27220)
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 processing untrusted input with a regular expressions in CGI::Util#escapeElement. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
6) Input validation error (CVE-ID: CVE-2025-27219)
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 input in CGI::Cookie.parse. A remote attacker can send a specially crafted HTTP request to the application and perform a denial of service (DoS) attack.
7) Information disclosure (CVE-ID: CVE-2025-27221)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:H/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 URI#join, URI#merge, and URI#+ methods retain sensitive information, such as user:password, even after the host is replaced. A remote attacker can gain access to sensitive information.
