CVE-2020-2756

CVSS v2.0

4.3

Medium

VectorAV:N/AC:M/Au:N/C:N/I:N/A:P
Name of the Vulnerable Software and Affected Versions Java SE versions 7u251, 8u241, 11.0.6, and 14 Java SE Embedded version 8u241
Description The issue is related to the Serialization component and is difficult to exploit, allowing an unauthenticated attacker with network access via multiple protocols to compromise Java SE and Java SE Embedded. Successful attacks can result in a partial denial of service. This issue can be exploited through sandboxed Java Web Start applications, sandboxed Java applets, or by supplying data to APIs in the specified component.
Recommendations For Java SE versions 7u251, 8u241, 11.0.6, and 14, consider disabling the Serialization component until a patch is available. For Java SE Embedded version 8u241, restrict access to the Serialization component to minimize the risk of exploitation. As a temporary workaround, avoid using APIs in the Serialization component without proper validation and sanitization of input data. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
