webdriver in IBM Informix Web DataBlade 4.12 allows remote attackers to bypass user access levels or read arbitrary files via a SQL injection attack in an HTTP request.

IBM Informix Web DataBlade 4.12 unescapes user input even if an application has escaped it, which could allow remote attackers to execute SQL code in a web form even when the developer has attempted to escape it.

Buffer overflow in sqlexec for Informix SE-7.25 allows local users to gain root privileges via a long INFORMIXDIR environment variable.

Stack-based buffer overflow in ontape for IBM Informix Dynamic Server (IDS) 9.40.xC3 and earlier allows local users, with DSA privileges, to execute arbitrary code via a long ONCONFIG environment variable.

IBM Informix Dynamic Server (IDS) before 9.40.xC3 allows local users to (1) create or overwrite files via the /001 log file to onedcu or (2) read arbitrary files via a symlink attack on a file in /tmp to onshowaudit.

Format string vulnerability in IBM Informix Dynamic Server (IDS) before 9.40.xC3 allows local users to execute arbitrary code via a modified INFORMIXDIR environment variable that points to a file with format string specifiers in the filename.

Buffer overflow in IBM Informix Dynamic Server (IDS) 9.40.xC1 and 9.40.xC2 allows local users to execute arbitrary code via a long GL_PATH environment variable.

IBM Informix Dynamic Database server running on Windows XP with Simple File Sharing enabled, allows remote attackers to bypass authentication and log on to the guest account by supplying an invalid username.

Buffer overflow in IBM Informix Dynamic Server (IDS) before 9.40.TC7 and 10.00 before 10.00.TC3, when running on Windows, allows remote attackers to execute arbitrary code via a long username.

Buffer overflow in IBM Informix Dynamic Server (IDS) 9.40.TC7, 9.40.TC8, 10.00.TC4, and 10.00.TC5, when running on Windows, allows remote attackers to execute arbitrary code via a long username, which causes an overflow in vsprintf when displaying in the resulting error message. NOTE: this issue is due to an incomplete fix for CVE-2006-3853.

The ifx_load_internal function in IBM Informix Dynamic Server (IDS) allows remote authenticated users to execute arbitrary C code via the DllMain or _init function in a library, aka "C code UDR."

IBM Informix Dynamic Server (IDS) before 9.40.xC7 and 10.00 before 10.00.xC3 allows local users to cause a denial of service (crash) via unspecified vectors.

Multiple buffer overflows in IBM Informix Dynamic Server (IDS) before 9.40.TC6 and 10.00 before 10.00.TC3 allow remote authenticated users to execute arbitrary code via (1) the getname function, as used by (a) _sq_remview, (b) _sq_remproc, (c) _sq_remperms, (d) _sq_distfetch, and (e) _sq_dcatalog; and the (2) SET DEBUG FILE, (3) IFX_FILE_TO_FILE, (4) FILETOCLOB, (5) LOTOFILE, and (6) DBINFO functions (product defect IDs 171649, 171367, 171387, 171391, 171906, 172179).

IBM Informix Dynamic Server (IDS) before 9.40.xC8 and 10.00 before 10.00.xC4 stores passwords in plaintext in shared memory, which allows local users to obtain passwords by reading the memory (product defects 171893, 171894, 173772).

IBM Informix Dynamic Server Authentication Bypass

IBM Informix Dynamic Server 14.10 could allow a local user on the system to log into the Informix server as administrator without a password.

IBM Informix Dynamic Server denial of service

IBM Informix Dynamic Server 12.10,14.10, and15.0 could allow a remote attacker to cause a denial of service due to an integer underflow when processing packets.

IBM Informix Dynamic Server information disclosure

IBM Informix Dynamic Server 12.10 and 14.10 uses an inadequate account lockout setting that could allow a remote attacker to brute force account credentials.

IBM Informix Dynamic Server HTML injection

IBM Informix Dynamic Server 12.10 and 14.10 is vulnerable to HTML injection. A remote attacker could inject malicious HTML code, which when viewed, would be executed in the victim's Web browser within the security context of the hosting site.

IBM Informix Dynamic Server buffer overflow

IBM Informix Dynamic Server 12.10 and 14.10 onsmsync is vulnerable to a heap buffer overflow, caused by improper bounds checking which could allow an attacker to execute arbitrary code. IBM X-Force ID: 250753.

IBM Informix Open Admin Tool 11.5, 11.7, and 12.1 could allow an unauthorized user to execute arbitrary code as system admin on Windows servers. IBM X-Force ID: 120390.
