CVE-2015-7392
HighSummary
Heap-based buffer overflow in the parse_string function in libs/esl/src/esl_json.c in FreeSWITCH before 1.4.23 and 1.6.x before 1.6.2. A remote attacker can exploit a trailing \u in a JSON string passed to cJSON_Parse, leading to arbitrary code execution.
Risk Assessment
The risk for the organization includes the possibility of remote takeover of the FreeSWITCH server, potentially compromising confidentiality, integrity, and availability of the system.
Recommendation
It is recommended to immediately upgrade FreeSWITCH to version 1.4.23 or later (for the 1.4.x branch) and to version 1.6.2 or later (for the 1.6.x branch).
