Synopsis

The remote web application server is affected by a vulnerability.

Description

The version of IBM WebSphere Application Server running on the remote host is affected by a vulnerability as referenced in the 7295372 advisory.

- Allocation of resources without limits or throttling (CWE-770) during Java object deserialization in Google Guava versions 4.0 through 33.7.1 allows an attacker to cause a Denial of Service via OutOfMemoryError. When deserializing CompactHashMap, CompactHashSet, or MapMakerInternalMap instances, Guava eagerly allocates an array based on a caller-specified size parameter without throttling, permitting memory exhaustion from crafted serialization streams. (CVE-2026-102554)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update to IBM WebSphere Application Server version 8.5.5.32, 9.0.5.30 or later.
