Memory-corruption in IBM Db2's IXF file IMPORT parser lets an attacker supply a crafted IXF data file that overflows a stack buffer (CWE-121), affecting Db2 11.5.0 through 11.5.9 and 12.1.0 through 12.1.5 on all listed platforms. Successful exploitation can crash the database engine or lead to code execution in the Db2 server process, yielding total loss of confidentiality, integrity, and availability. IBM has released a fix; there is no public exploit identified at time of analysis and CISA SSVC currently rates exploitation as 'none'.
Privilege escalation in IBM Db2 (data server versions 11.5.0-11.5.9 and 12.1.0-12.1.5) allows an attacker to submit a specially crafted query that bypasses authorization controls and gains elevated database privileges, classified as CWE-285 improper authorization. IBM reported the issue and has published a fix; there is no public exploit identified at time of analysis and it is not on CISA KEV. EPSS is low at 0.32% (25th percentile) despite the 9.8 CVSS, indicating no observed mass-exploitation activity yet.
IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.5 expose an improper authorization flaw in certain database commands, enabling a low-privileged authenticated user to bypass server-side authority checks and directly modify database catalog data. The root cause is CWE-602 (client-side enforcement of server-side security), where authorization validation is not properly enforced at the server layer. No public exploit has been identified and SSVC rates exploitation as none currently, though the high integrity impact against catalog metadata - which governs schema definitions and access control structures - makes this a meaningful patching priority for all affected Db2 deployments.
IBM Db2 on Linux, UNIX, and Windows exposes cleartext database passwords by writing them into diagnostic trace files, affecting versions 11.5.0-11.5.9 and 12.1.0-12.1.5, including DB2 Connect Server. Any low-privilege local OS user with read access to the Db2 trace directory can harvest plaintext credentials without requiring database-level authentication or elevated system rights. IBM has released a patch; no active exploitation has been confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis.
Memory leak denial of service in IBM Db2 12.1.5 for Linux, UNIX, and Windows (including DB2 Connect Server) enables a local attacker with low-privilege credentials to exhaust system resources and degrade database availability. Rooted in CWE-770 (uncontrolled resource allocation), the flaw requires no user interaction beyond an authenticated local session. No public exploit code or active exploitation is identified; IBM has released a patch via its support portal.
Stack-based buffer overflow in IBM Db2's setgid helper binary db2flacc allows a local user with low privileges to overwrite the stack frame and execute arbitrary code with the elevated group permissions of the binary. Both Db2 11.5.x (through 11.5.9) and 12.1.x (through 12.1.4) are affected. No public exploit has been identified and exploitation status is confirmed as none per SSVC, though IBM has released a patch and the SSVC technical impact is rated total, warranting prompt remediation on shared-access Db2 hosts.
Denial of service in IBM Db2 federated server (versions 12.1.0 through 12.1.4) can be triggered by executing non-fenced federated queries, causing the database engine to exhaust resources and become unresponsive. The root cause is CWE-400 (Uncontrolled Resource Consumption) within the in-process federated wrapper execution path. No public exploit has been identified at time of analysis, and IBM has released a patch via their support portal.
Denial of service in IBM Db2 11.5.x and 12.1.x allows a local database user to crash the database engine by submitting specially crafted SQL statements containing subqueries that trigger an infinite loop (CWE-835) in the query compiler. The vulnerability spans two active major release lines - 11.5.0 through 11.5.9 and 12.1.0 through 12.1.4 - covering a broad swath of IBM's current Db2 product lifecycle. No public exploit code or active exploitation has been identified at time of analysis; IBM has released a patch via the vendor advisory.
Code injection leading to remote code execution affects IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.4 when an attacker can influence the JDBC connection URL passed to the driver. An attacker who controls the JDBC URL (typically via an application that builds connection strings from user input) can inject malicious properties or references that cause arbitrary code to execute in the context of the connecting application/driver host. IBM has released a fix; there is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Denial of service in IBM Db2 11.5.0-11.5.9 and 12.1.0-12.1.4 allows an authenticated low-privileged user to crash or hang the database server by submitting a crafted SQL query exploiting improper neutralization of special elements in XMLTable-derived column processing logic. The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H) confirms this is remotely triggerable with minimal privileges, posing a realistic insider-threat or compromised-credential availability risk. No public exploit code or active exploitation has been identified at time of analysis.
Remote code execution in IBM Db2 11.5.0-11.5.9 and 12.1.0-12.1.4 lets unauthenticated network attackers run arbitrary code by abusing improper handling of the pre-authentication DRDA handshake. Because the flaw is reachable before any login, any client able to reach the database listener can trigger it, and the CVSS 3.1 base score of 9.8 reflects full compromise of confidentiality, integrity, and availability. No public exploit is identified at time of analysis and the CVE is not listed in CISA KEV.
IBM Db2 versions 11.5.0-11.5.9 and 12.1.0-12.1.4 expose sensitive information through internal monitoring and event tables to authenticated low-privilege local users, a consequence of CWE-538 where sensitive data is inserted into storage locations accessible beyond the intended trust boundary. The CVSS vector confirms local-only attack surface (AV:L) with low-privilege authentication (PR:L) and high confidentiality impact, making this most relevant to insider threat scenarios or post-compromise lateral movement in multi-tenant Db2 environments. No public exploit code exists and the vulnerability is not listed in CISA KEV, indicating no confirmed active exploitation at time of analysis.
IBM Db2 on Linux, UNIX, and Windows - versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.4, including DB2 Connect Server - writes potentially sensitive information into log files readable by local OS users, creating an insider-threat-class confidentiality exposure. The CVSS confidentiality impact is rated High (C:H), but the attack is strictly local (AV:L) and requires only a standard low-privilege OS account (PR:L), making this a post-access or insider-threat scenario rather than an internet-facing risk. No public exploit has been identified at time of analysis, EPSS sits at the 2nd percentile (0.01%), and CISA SSVC records no active exploitation - IBM has released a patch addressed in advisory https://www.ibm.com/support/pages/node/7273554.

Rooted in CWE-770 (uncontrolled resource allocation), the flaw requires no user interaction beyond an authenticated local session. No public exploit code or active exploitation is identified; IBM has released a patch via its support portal.
Stack-based buffer overflow in IBM Db2's setgid helper binary db2flacc allows a local user with low privileges to overwrite the stack frame and execute arbitrary code with the elevated group permissions of the binary. Both Db2 11.5.x (through 11.5.9) and 12.1.x (through 12.1.4) are affected. No public exploit has been identified and exploitation status is confirmed as none per SSVC, though IBM has released a patch and the SSVC technical impact is rated total, warranting prompt remediation on shared-access Db2 hosts.
Denial of service in IBM Db2 federated server (versions 12.1.0 through 12.1.4) can be triggered by executing non-fenced federated queries, causing the database engine to exhaust resources and become unresponsive. The root cause is CWE-400 (Uncontrolled Resource Consumption) within the in-process federated wrapper execution path. No public exploit has been identified at time of analysis, and IBM has released a patch via their support portal.
Denial of service in IBM Db2 11.5.x and 12.1.x allows a local database user to crash the database engine by submitting specially crafted SQL statements containing subqueries that trigger an infinite loop (CWE-835) in the query compiler. The vulnerability spans two active major release lines - 11.5.0 through 11.5.9 and 12.1.0 through 12.1.4 - covering a broad swath of IBM's current Db2 product lifecycle. No public exploit code or active exploitation has been identified at time of analysis; IBM has released a patch via the vendor advisory.
Code injection leading to remote code execution affects IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.4 when an attacker can influence the JDBC connection URL passed to the driver. An attacker who controls the JDBC URL (typically via an application that builds connection strings from user input) can inject malicious properties or references that cause arbitrary code to execute in the context of the connecting application/driver host. IBM has released a fix; there is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Denial of service in IBM Db2 11.5.0-11.5.9 and 12.1.0-12.1.4 allows an authenticated low-privileged user to crash or hang the database server by submitting a crafted SQL query exploiting improper neutralization of special elements in XMLTable-derived column processing logic. The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H) confirms this is remotely triggerable with minimal privileges, posing a realistic insider-threat or compromised-credential availability risk. No public exploit code or active exploitation has been identified at time of analysis.
Remote code execution in IBM Db2 11.5.0-11.5.9 and 12.1.0-12.1.4 lets unauthenticated network attackers run arbitrary code by abusing improper handling of the pre-authentication DRDA handshake. Because the flaw is reachable before any login, any client able to reach the database listener can trigger it, and the CVSS 3.1 base score of 9.8 reflects full compromise of confidentiality, integrity, and availability. No public exploit is identified at time of analysis and the CVE is not listed in CISA KEV.
IBM Db2 versions 11.5.0-11.5.9 and 12.1.0-12.1.4 expose sensitive information through internal monitoring and event tables to authenticated low-privilege local users, a consequence of CWE-538 where sensitive data is inserted into storage locations accessible beyond the intended trust boundary. The CVSS vector confirms local-only attack surface (AV:L) with low-privilege authentication (PR:L) and high confidentiality impact, making this most relevant to insider threat scenarios or post-compromise lateral movement in multi-tenant Db2 environments. No public exploit code exists and the vulnerability is not listed in CISA KEV, indicating no confirmed active exploitation at time of analysis.
IBM Db2 on Linux, UNIX, and Windows - versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.4, including DB2 Connect Server - writes potentially sensitive information into log files readable by local OS users, creating an insider-threat-class confidentiality exposure. The CVSS confidentiality impact is rated High (C:H), but the attack is strictly local (AV:L) and requires only a standard low-privilege OS account (PR:L), making this a post-access or insider-threat scenario rather than an internet-facing risk. No public exploit has been identified at time of analysis, EPSS sits at the 2nd percentile (0.01%), and CISA SSVC records no active exploitation - IBM has released a patch addressed in advisory https://www.ibm.com/support/pages/node/7273554.
