Name of the Vulnerable Software and Affected Versions
Archive Tar versions 1.4.10 and earlier
Description
The issue allows an unserialization attack because
phar: is blocked but PHAR: is not blocked. This can be exploited by a remote attacker to execute arbitrary PHP code using a specially crafted .tar archive. The vulnerability is related to the restoration of an untrusted data structure in memory.Recommendations
For Archive Tar versions 1.4.10 and earlier, consider disabling the use of
PHAR: until a patch is available. As a temporary workaround, restrict the use of the Archive Tar class to minimize the risk of exploitation. Avoid using specially crafted .tar archives that could trigger the unserialization attack.قابلية الاستغلال
