Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) OS Command Injection
EUVDB-ID: #VU69808
Risk: High
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-45939
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation when processing name of a source-code file in lib-src/etags.c. A remote attacker can trick the victim to use the "ctags *" command and execute arbitrary OS commands on the target system in a situation where the current working directory has contents that depend on untrusted input.

CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation when parsing name of a source-code file in lib-src/etags.c. A remote attacker can trick the victim use the "etags -u *" command on the directory with attacker controlled content and execute arbitrary OS commands on the target system.

3) OS Command Injection
EUVDB-ID: #VU72575
Risk: High
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-48339
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation within the hfy-istext-command() function when parsing the "file" and "srcdir" parameters, if a file name or directory name contains shell metacharacter. A remote attacker can execute arbitrary OS commands on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
