Title
Kamailio Configuration File rvalue.c rve_destroy heap-based overflow
Summary
A security vulnerability has been detected in Kamailio 5.5. Impacted is the function rve_destroy of the file src/core/rvalue.c of the component Configuration File Handler. The manipulation leads to heap-based buffer overflow. The attack must be carried out locally. The exploit has been disclosed publicly and may be used. There is ongoing doubt regarding the real existence of this vulnerability. This attack requires manipulating config files which might not be a realistic scenario in many cases. The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2020-28361 (GCVE-0-2020-28361)
Vulnerability from cvelistv5 – Published: 2020-11-18 13:34 – Updated: 2024-08-04 16:33
VLAI?
Summary
Kamailio before 5.4.0, as used in Sip Express Router (SER) in Sippy Softswitch 4.5 through 5.2 and other products, allows a bypass of a header-removal protection mechanism via whitespace characters. This occurs in the remove_hf function in the Kamailio textops module. Particular use of remove_hf in Sippy Softswitch may allow skilled attacker having a valid credential in the system to disrupt internal call start/duration accounting mechanisms leading potentially to a loss of revenue.

CVE-2018-16657 (GCVE-0-2018-16657)
Vulnerability from cvelistv5 – Published: 2018-09-07 14:00 – Updated: 2024-08-05 10:32
VLAI?
Summary
In Kamailio before 5.0.7 and 5.1.x before 5.1.4, a crafted SIP message with an invalid Via header causes a segmentation fault and crashes Kamailio. The reason is missing input validation in the crcitt_string_array core function for calculating a CRC hash for To tags. (An additional error is present in the check_via_address core function: this function also misses input validation.) This could result in denial of service and potentially the execution of arbitrary code.

CVE-2018-14767 (GCVE-0-2018-14767)
Vulnerability from cvelistv5 – Published: 2018-07-31 06:00 – Updated: 2024-08-05 09:38
VLAI?
Summary
In Kamailio before 5.0.7 and 5.1.x before 5.1.4, a crafted SIP message with a double "To" header and an empty "To" tag causes a segmentation fault and crash. The reason is missing input validation in the "build_res_buf_from_sip_req" core function. This could result in denial of service and potentially the execution of arbitrary code.
Severity ?
No CVSS data available.
