CVE-2025-12207 1 Kamailio 1 Kamailio 2025-10-28 3.3 Low
A vulnerability has been found in Kamailio 5.5. This affects the function yyerror_at of the file src/core/cfg.y of the component Grammar Rule Handler. Such manipulation leads to null pointer dereference. The attack needs to be performed locally. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2025-12206 1 Kamailio 1 Kamailio 2025-10-28 3.3 Low
A flaw has been found in Kamailio 5.5. The impacted element is the function rve_is_constant of the file src/core/rvalue.c. This manipulation causes null pointer dereference. The attack needs to be launched locally. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2025-12205 1 Kamailio 1 Kamailio 2025-10-28 5.3 Medium
A vulnerability was detected in Kamailio 5.5. The affected element is the function sr_push_yy_state of the file src/core/cfg.lex of the component Configuration File Handler. The manipulation results in use after free. The attack must be initiated from a local position. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2025-12204 1 Kamailio 1 Kamailio 2025-10-28 5.3 Medium
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. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2015-1590 1 Kamailio 1 Kamailio 2025-04-20 N/A
The kamcmd administrative utility and default configuration in kamailio before 4.3.0 use /tmp/kamailio_ctl.
CVE-2013-7426 1 Kamailio 1 Kamailio 2025-04-20 N/A
Insecure Temporary file vulnerability in /tmp/kamailio_fifo in kamailio 4.0.1.
CVE-2015-1591 1 Kamailio 1 Kamailio 2025-04-20 N/A
The kamailio build in kamailio before 4.2.0-2 process allows local users to gain privileges.
CVE-2016-2385 2 Debian, Kamailio 2 Debian Linux, Kamailio 2025-04-12 N/A
Heap-based buffer overflow in the encode_msg function in encode_msg.c in the SEAS module in Kamailio (formerly OpenSER and SER) before 4.3.5 allows remote attackers to cause a denial of service (memory corruption and process crash) or possibly execute arbitrary code via a large SIP packet.
CVE-2020-27507 1 Kamailio 1 Kamailio 2025-02-27 9.8 Critical
The Kamailio SIP before 5.5.0 server mishandles INVITE requests with duplicated fields and overlength tag, leading to a buffer overflow that crashes the server or possibly have unspecified other impact.
CVE-2020-28361 1 Kamailio 1 Kamailio 2024-11-21 5.4 Medium
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-2018-8828 2 Debian, Kamailio 2 Debian Linux, Kamailio 2024-11-21 N/A
A Buffer Overflow issue was discovered in Kamailio before 4.4.7, 5.0.x before 5.0.6, and 5.1.x before 5.1.2. A specially crafted REGISTER message with a malformed branch or From tag triggers an off-by-one heap-based buffer overflow in the tmx_check_pretran function in modules/tmx/tmx_pretran.c.
CVE-2018-16657 2 Debian, Kamailio 2 Debian Linux, Kamailio 2024-11-21 N/A
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 2 Debian, Kamailio 2 Debian Linux, Kamailio 2024-11-21 N/A
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.
