CVE-2022-46140
https://notcve.org/view.php?id=CVE-2022-46140
Affected devices use a weak encryption scheme to encrypt the debug zip file. This could allow an authenticated attacker to decrypt the contents of the file and retrieve debug information about the system. Los dispositivos afectados utilizan un esquema de cifrado débil para cifrar el archivo zip de depuración. Esto podría permitir a un atacante autenticado descifrar el contenido del archivo y recuperar información de depuración sobre el sistema. • https://cert-portal.siemens.com/productcert/pdf/ssa-413565.pdf • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVE-2022-46142
https://notcve.org/view.php?id=CVE-2022-46142
Affected devices store the CLI user passwords encrypted in flash memory. Attackers with physical access to the device could retrieve the file and decrypt the CLI user passwords. Los dispositivos afectados almacenan las contraseñas de usuario de CLI cifradas en la memoria flash. Los atacantes con acceso físico al dispositivo podrían recuperar el archivo y descifrar las contraseñas de usuario de la CLI. • https://cert-portal.siemens.com/productcert/pdf/ssa-413565.pdf • CWE-257: Storing Passwords in a Recoverable Format CWE-522: Insufficiently Protected Credentials •
CVE-2022-46143
https://notcve.org/view.php?id=CVE-2022-46143
Affected devices do not check the TFTP blocksize correctly. This could allow an authenticated attacker to read from an uninitialized buffer that potentially contains previously allocated data. Los dispositivos afectados no verifican correctamente el tamaño del bloque TFTP. Esto podría permitir que un atacante autenticado lea desde un búfer no inicializado que potencialmente contenga datos previamente asignados. • https://cert-portal.siemens.com/productcert/pdf/ssa-180704.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-413565.pdf https://cert-portal.siemens.com/productcert/html/ssa-413565.html https://cert-portal.siemens.com/productcert/html/ssa-180704.html • CWE-1284: Improper Validation of Specified Quantity in Input •
CVE-2022-32206 – curl: HTTP compression denial of service
https://notcve.org/view.php?id=CVE-2022-32206
curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a "malloc bomb", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors. curl versiones anteriores a 7.84.0, soporta algoritmos de compresión HTTP "encadenados", lo que significa que una respuesta al servidor puede ser comprimida múltiples veces y potencialmente con diferentes algoritmos. El número de "eslabones" aceptables en esta "cadena de descompresión" era ilimitado, lo que permitía a un servidor malicioso insertar un número prácticamente ilimitado de pasos de compresión. El uso de una cadena de descompresión de este tipo podía resultar en una "bomba de malloc", haciendo que curl acabara gastando enormes cantidades de memoria de montón asignada, o intentando y devolviendo errores de memoria A vulnerability was found in curl. This issue occurs because the number of acceptable "links" in the "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps. • http://seclists.org/fulldisclosure/2022/Oct/28 http://seclists.org/fulldisclosure/2022/Oct/41 http://www.openwall.com/lists/oss-security/2023/02/15/3 https://cert-portal.siemens.com/productcert/pdf/ssa-333517.pdf https://hackerone.com/reports/1570651 https://lists.debian.org/debian-lts-announce/2022/08/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BEV6BR4MTI3CEWK2YU2HQZUW5FAS3FEY https://security.gentoo.org/glsa/202212-01 https:/ • CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2022-32205
https://notcve.org/view.php?id=CVE-2022-32205
A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on `foo.example.com` can set cookies that also would match for `bar.example.com`, making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method. Un servidor malicioso puede servir cantidades excesivas de encabezados "Set-Cookie:" en una respuesta HTTP a curl y curl versiones anteriores a 7.84.0 las almacena todas. Una cantidad suficientemente grande de cookies (grandes) hace que las subsiguientes peticiones HTTP a este, o a otros servidores con los que coincidan las cookies, creen peticiones que superen el umbral que curl usa internamente para evitar el envío de peticiones locamente grandes (1048576 bytes) y en su lugar devuelva un error. • http://seclists.org/fulldisclosure/2022/Oct/28 http://seclists.org/fulldisclosure/2022/Oct/41 https://cert-portal.siemens.com/productcert/pdf/ssa-333517.pdf https://hackerone.com/reports/1569946 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BEV6BR4MTI3CEWK2YU2HQZUW5FAS3FEY https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20220915-0003 https://support.apple.com/kb/HT213488 https://www.debian.org/security/2022/dsa- • CWE-770: Allocation of Resources Without Limits or Throttling •
