critical Nessus Plugin ID 187329

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 6.06, has expat packages installed that are affected by multiple vulnerabilities:

- In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
(CVE-2021-45960)

- In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for m_groupSize. (CVE-2021-46143)

- addBinding in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22822)

- build_model in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22823)

- defineAttribute in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.
(CVE-2022-22824)

- lookup in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22825)

- nextScaffoldPart in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.
(CVE-2022-22826)

- storeAtts in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22827)

- Expat (aka libexpat) before 2.4.4 has a signed integer overflow in XML_GetBuffer, for configurations with a nonzero XML_CONTEXT_BYTES. (CVE-2022-23852)

- xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks for whether a UTF-8 character is valid in a certain context. (CVE-2022-25235)

- xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters into namespace URIs. (CVE-2022-25236)

- In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

- libexpat before 2.4.9 has a use-after-free in the doContent function in xmlparse.c. (CVE-2022-40674)

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

Solution

Upgrade the vulnerable CGSL expat packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
