https://notcve.org/view.php?id=CVE-2020-28949
Archive_Tar through 1.4.10 has :// filename sanitization only to address phar attacks, and thus any other stream-wrapper attack (such as file:// to overwrite files) can still succeed. Archive_Tar versiones hasta 1.4.10, presenta una desinfección del nombre de archivo :// solo para abordar los ataques phar y, por lo tanto, cualquier otro ataque de empaquetado de flujo (tal y como file:// para sobrescribir archivos) aún puede tener éxito A flaw was found in the Archive_Tar package. PEAR Archive_Tar could allow a local authenticated attacker to bypass security restrictions caused by a stream-wrapper attack. An attacker can overwrite arbitrary files on the system using a specially-crafted tar archive. PEAR Archive_Tar allows an unserialization attack because phar: is blocked but PHAR: is not blocked. • https://github.com/0x240x23elu/CVE-2020-28948-and-CVE-2020-28949 https://github.com/JinHao-L/PoC-for-CVE-2020-28948-CVE-2020-28949 http://packetstormsecurity.com/files/161095/PEAR-Archive_Tar-Arbitrary-File-Write.html https://github.com/pear/Archive_Tar/issues/33 https://lists.debian.org/debian-lts-announce/2020/11/msg00045.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/42GPGVVFTLJYAKRI75IVB5R45NYQGEUR https://lists.fedoraproject.org/archives/list/pack • CWE-20: Improper Input Validation CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
